15.	The compound interest on a sum of money for 2 yearsis 50 and the simple interest on the same sum, for thesame period and at the same rate is 48. Find the rate
Answer» Question :- The COMPOUND INTEREST on a sum of money for 2 years is 50 and the simple interest on the same sum, for the same period and at the same RATE is 48. Find the rate. Answer :- → Rate (r) = 8 % To Find :- → Rate Solution :- Given that : Compound interest (C.I) for 2 YEAR = 50 Simple interest (S.I) for 2 years = 48 → Simple interest and compound interest for first year is same , hence, → S.I for first year = $\sf \dfrac{50}{2} =Rs. \:25$ therefore , → C.I for second year = 52 - 25 =Rs. 27 Hence , difference is 27 - 25 = Rs. 2 → Rs. 2 on first year interest of Rs. 25 So, rate(r) will be - $\to \sf 2= \frac{25 \times r \times 1}{100} \\ \\ \to \sf \: 200 = 25 \times r \: \\ \\ \to \sf r = \frac{200}{25} \\ \\ \to \boxed{\sf \: r = 8 \%}$ hence rate is 8% .

The compound interest on a sum of money for 2 yearsis 50 and the simple interest on the same sum, for thesame period and at the same rate is 48. Find the rate

Answer»

Question :-

The COMPOUND INTEREST on a sum of money for 2 years is 50 and the simple interest on the same sum, for the same period and at the same RATE is 48. Find the rate.

Answer :-

→ Rate (r) = 8 %

To Find :-

→ Rate

Solution :-

Given that :

Compound interest (C.I) for 2 YEAR = 50
Simple interest (S.I) for 2 years = 48

→ Simple interest and compound interest for first year is same ,

hence,

→ S.I for first year = $\sf \dfrac{50}{2} =Rs. \:25$

therefore ,

→ C.I for second year = 52 - 25 =Rs. 27

Hence , difference is 27 - 25 = Rs. 2

→ Rs. 2 on first year interest of Rs. 25

So, rate(r) will be -

$\to \sf 2= \frac{25 \times r \times 1}{100} \\ \\ \to \sf \: 200 = 25 \times r \: \\ \\ \to \sf r = \frac{200}{25} \\ \\ \to \boxed{\sf \: r = 8 \%}$

hence rate is 8% .

16.	Find the area of rhombuswhose diagonal are ( x+2) and (x-7)
Answer» Step-by-step EXPLANATION: Area of RHOMBUS = 1/2 ×d1×d2 Diagonals are given : (x+2 ) and (x-7) We can APPLY this formula for rhombus we know that there are 2 diagonal in a rhombus and it's of 1/2 So we can FIND it 1/2 × (x+2) ×(x-7) = ( x²-7x+2x-14 ) 2 = (x²-5x-14) / 2 = [ x²-(7-2)x-14] / 2 = (x²-7x+2x-14) / 2 = [X ( x-7) +2 (x-7) ] / 2 = [ (x-7) (x+2) ] / 2 Ans Hence the ANSWER is 2

16.

Find the area of rhombuswhose diagonal are ( x+2) and (x-7)

Answer»

Step-by-step EXPLANATION:

Area of RHOMBUS = 1/2 ×d1×d2

Diagonals are given : (x+2 ) and (x-7)

We can APPLY this formula

for rhombus we know that there are 2 diagonal in a rhombus and it's of 1/2

So we can FIND it

1/2 × (x+2) ×(x-7)

= ( x²-7x+2x-14 ) 2

= (x²-5x-14) / 2

= [ x²-(7-2)x-14] / 2

= (x²-7x+2x-14) / 2

= [X ( x-7) +2 (x-7) ] / 2

= [ (x-7) (x+2) ] / 2 Ans

Hence the ANSWER is 2

35.	Swati control board at a speed of 5 kilometre per hour in still water takes 1 hour more to Row the board 5.25 km upstream then to return downstream find the speed of the stream
Answer» Answer: The speed of stream is 2 KM/h Step-by-step explanation: Given as : Let The speed of stream = x km/h Speed of boat in UPSTREAM = (5 -x) km/h Speed of boat in down stream = (5 + x) km/h Time TAKEN to move 5.5 km upstream = $t_1$ = $\dfrac{5.5}{5 - x}$ hours And , Time taken to move 5.5 km downstream = $t_2$ = $\dfrac{5.5}{5+x}$ hours ∵ $t_1$ = 1 + $t_2$ Or, $\dfrac{5.5}{5 - x}$ = 1 + $\dfrac{5.5}{5+x}$ Or, $\dfrac{5.5}{5 - x}$ - $\dfrac{5.5}{5+x}$ = 1 Or, 5.5 ( 5 + x) - 5.5 ( 5 - x) = (5 - x) (5 + x) Or, 27.5 + 5.5 x - 27.5 + 5.5 x = 25 + 5 x - 5 x - x² Or, 0 + 11 x = 25 + 0 - x² Or, x ² + 11 x - 25 = 0 Now, Solving this quadratic EQUATION x = 1.9 ≈ 2 km/h And x = - 12.9 ≈ - 13 So, The speed of stream = x = 2 km/h Hence, The speed of stream is 2 km/h Answer

35.

Swati control board at a speed of 5 kilometre per hour in still water takes 1 hour more to Row the board 5.25 km upstream then to return downstream find the speed of the stream

Answer»

Answer:

The speed of stream is 2 KM/h

Step-by-step explanation:

Given as :

Let The speed of stream = x km/h

Speed of boat in UPSTREAM = (5 -x) km/h

Speed of boat in down stream = (5 + x) km/h

Time TAKEN to move 5.5 km upstream = $t_1$ = $\dfrac{5.5}{5 - x}$ hours

And , Time taken to move 5.5 km downstream = $t_2$ = $\dfrac{5.5}{5+x}$ hours

∵ $t_1$ = 1 + $t_2$

Or, $\dfrac{5.5}{5 - x}$ = 1 + $\dfrac{5.5}{5+x}$

Or, $\dfrac{5.5}{5 - x}$ - $\dfrac{5.5}{5+x}$ = 1

Or, 5.5 ( 5 + x) - 5.5 ( 5 - x) = (5 - x) (5 + x)

Or, 27.5 + 5.5 x - 27.5 + 5.5 x = 25 + 5 x - 5 x - x²

Or, 0 + 11 x = 25 + 0 - x²

Or, x ² + 11 x - 25 = 0

Now, Solving this quadratic EQUATION

x = 1.9 ≈ 2 km/h

And x = - 12.9 ≈ - 13

So, The speed of stream = x = 2 km/h

Hence, The speed of stream is 2 km/h Answer

Answer» Answer:97 Step-by-step explanation: LET the UNIT's place be x. And TEN's place will be (x+2). Original number=10(x+2)+x =10x+20+x =11x+20 Reversed number=10(x)+x+2 =10x+x+2 =11x+2 11x+2+11x+20=176 22x+22=176 x+1=8 x=8-1 x=7 Therefore, original number =10(7+2)+7 =10*9+7 =90+7 =97

50.

the sum of two digit number and the number obtained by reversing its digit is 176 find the number if its ten's place digit is greater than the units place digit by 2

Answer»

Answer:97

Step-by-step explanation:

LET the UNIT's place be x. And TEN's place will be (x+2).

Original number=10(x+2)+x

=10x+20+x

=11x+20

Reversed number=10(x)+x+2

=10x+x+2

=11x+2

11x+2+11x+20=176

22x+22=176

x+1=8

x=8-1

x=7

Therefore, original number =10(7+2)+7

=10*9+7

=90+7

=97
