7.

Sub the sum of -3/10 and 5/8 from the sum of 4/15 and 2/-5

Answer»

Step-by-step explanation:

-3/10+5/8 = -12+25/40= 13/40

4/15+(2/-5)= 4/15-2/5=4-6/15=-2/15

[{4/15+(2/-5)} - {-3/10+5/8}] = -2/15 + 13/40

[{4/15+(2/-5)} - {-3/10+5/8}] = (-16+30)/120

19.	X is a number between 3 million and 4 million if i divide X by 100 thousand the sum of the digits of the quotient is 5 if i divide X by 10,000, the sum of the digits of the quotient is 12 if i divide X by 1000,the sum of the digits of the quotient is 18 when X is divided by 100 ,the remainder is 84 the sum of the digits of X is 39 . can you find X?
Answer» Answer:3276984 Step-by-step explanation: X should be a 7 digit number Division by 100 gives remainder 84 which means last 2 DIGITS of the number X is 84 X lies between 3 M and 4M so first digit of X is 3 Now by DIVIDING X by 100,000 gives a quotient whose sum is 5, which means the quotient will be a decimal with 5 decimal place, so X COULD be 3? . ???84, so quotient will be 3? which means 32 since sum should be 5 Likewise on dividing by 10,000 decimal places will be 4, 32?.??84, So quotient will be 327, to MAKE sum 12 Likewise on dividing by 1000, quotient will be 3276 to make sum 18 So we get: 3276?84 Sum: 3+2+7+6+8+4= 30 Given Sum of digits of X: 39 thus final original number will be 3276984

X is a number between 3 million and 4 million if i divide X by 100 thousand the sum of the digits of the quotient is 5 if i divide X by 10,000, the sum of the digits of the quotient is 12 if i divide X by 1000,the sum of the digits of the quotient is 18 when X is divided by 100 ,the remainder is 84 the sum of the digits of X is 39 . can you find X?

Answer»

Answer:3276984

Step-by-step explanation:

X should be a 7 digit number

Division by 100 gives remainder 84 which means last 2 DIGITS of the number X is 84

X lies between 3 M and 4M so first digit of X is 3

Now by DIVIDING X by 100,000 gives a quotient whose sum is 5, which means the quotient will be a decimal with 5 decimal place, so X COULD be

3? . ???84, so quotient will be 3? which means 32 since sum should be 5

Likewise on dividing by 10,000 decimal places will be 4, 32?.??84, So quotient will be 327, to MAKE sum 12

Likewise on dividing by 1000, quotient will be 3276 to make sum 18

So we get: 3276?84

Sum: 3+2+7+6+8+4= 30

Given

Sum of digits of X: 39

thus final original number will be 3276984

AB and C invested their capital in ratio 2:3-4, at end of the business they received the profitin the ratio 5:6:7. Find the ratio of time period for which they contributed their capitals.

Answer»

Answer:

_______________________________

let the capital of A = x

capital of B = y

and capital of C = z

_______________________________

Given ratio of their capitals = 2 : 3 : 5

x : y : z = 2 : 3 : 5

let the P1 ,P2 ,P3 are the PROFITS they received

at the end of the business terms.

Given, ratio of their profits = 5 : 3 : 12

P1 : P2 : P3 = 5 : 3 : 12

According to the formula ,

Required ratio will be

_______________________________

= P1 / x : P2 / y : P3 / z

_______________________________

= 5 / 2 : 3 / 3 : 12 / 5

= 5 / 2 : 1 : 12 / 5

= 5 × 5 : 2 × 5 : 2 × 12

= 25 : 10 : 24

therefore,

ratio of time for which they contributed

= 25 : 10 : 24

49.

If Sin A = 3/5, Prove that tan A+ 1/CosA = 2.

Answer»

<P> $\bigstar$ $\boxed{\huge{\red{\mathfrak{Answer}}}}$ $\bigstar$

_________________________

SIN A = $\frac{P}{H}$

P → 3

H → 5

B → $\sqrt{25-9}$

B → $\sqrt{16}$

B → 4

_________________________

Taking L.H.S ,

$\frac{P}{H} + \frac{H}{B}$

$\frac{3}{5}+\frac{5}{4}$

$\frac{12+25}{20}$

$\frac{37}{20}$

L.H.S ≠ R.H.S

ESTIMATE (356+275=___) TO NEAREST TENS

Sub the sum of -3/10 and 5/8 from the sum of 4/15 and 2/-5

-3/10+5/8 = -12+25/40= 13/40

4/15+(2/-5)= 4/15-2/5=4-6/15=-2/15

[{4/15+(2/-5)} - {-3/10+5/8}] = -2/15 + 13/40

[{4/15+(2/-5)} - {-3/10+5/8}] = (-16+30)/120

[{4/15+(2/-5)} - {-3/10+5/8}] = 23/120
