13.	Largest no which divide 70 &125 leaving remainder 5and 8
Answer» Solution :- To find the largest number which divides 70 and 125 leaving the remainder 5 and 8 respectively, we will have to SUBTRACT 5 from 70 and 8 from 125 then we will compute the Highest Common Factor of those two number which we will get after subtracting. a) 70 - 5 = 65 b) 125 - 8 = 117 Now, we will compute the H.C.F. of 65 and 117. a) 65 b) 117 _______ ________ 5 \| 65, 3 \| 117 \|_______ \|________ 13 \| 13 3 \| 39 \|_______ \|________ \| 1 13 \| 13 \| \|________ \| 1 \| 13 is the only common factor of 65 and 117. Hence H.C.F. of 65 and 117 is 13 Therefore, 13 is the largest number which divides 70 and 125 leaving the remainder of 5 and 8 respectively. Let us check it. a) 70 ÷ 13Quotient = 5Remainder = 5 b) 125 ÷ 13Quotient = 9Remainder = 8 hope this helps have a nice day

44.	In a bag containing red and white balls half the number of white balls is equal to one third of red balls. Thrice the total number of balls exceeds seven times the number of white balls by 6. How many balls of each colour are there?
Answer» Let the NUMBER of red balls = x and white balls = y Given that, half the number of white balls is equal to one-third of red balls. Therefore y/2 = x/3 3y = 2x x = 3y/2 Also given that, thrice the total number of balls exceeds seven times the number of white balls by 6 Total number of balls = x + y Therefore 3(x + y) - 7y = 6 3x + 3y - 7y = 6 3x - 4y = 6 Substituting the value of x 3 (3y/2) - 4y = 6 9y/2 - 4y = 6 (9y - 8Y)/2 = 6 y = 12 x = 3*12/2 = 18 The number of red balls = 18 The number of white balls = 12 Hope this helps you.

50.	Compound interest on a certain sum of money at 5% per annum for two years is 246 Rs . Calculate simple interest on the same sum for 3 years at 6% per annum
Answer» Given:- <P> Rate = 5% Time = 2 YEARS C.I. = Rs 246 To find :- S.I. = ? Solution :- Formula $\implies$ $C.I. = P[(\dfrac{r}{100})^n - 1]$ Put the given values-- $246 = P[(\dfrac{5}{100})^2 - 1 ]$ $246 = P[ (\dfrac{1}{20})^2 - 1]$ $246 = P[ (\dfrac{21}{20})^2 - 1 ]$ $246 = P[ \dfrac{441-400}{400}]$ $246 = P[\dfrac{41}{400}]$ $\dfrac{246 \times 400}{41} = P$ P = Rs2400 ▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬ S.I. = ? Time = 3 years Rate = 6% Formula to find S.I. $S.I. = \dfrac{P \times R \times T}{100}$ Put the given values :- $\dfrac{2400 \times 6 \times 3}{100}$ $Rs~ 432$ Answer => S.I. = Rs 432

50.

Compound interest on a certain sum of money at 5% per annum for two years is 246 Rs . Calculate simple interest on the same sum for 3 years at 6% per annum

Answer»

Given:-

<P>

Rate = 5%

Time = 2 YEARS

C.I. = Rs 246

To find :-

S.I. = ?

Solution :-

Formula $\implies$

$C.I. = P[(\dfrac{r}{100})^n - 1]$

Put the given values--

$246 = P[(\dfrac{5}{100})^2 - 1 ]$

$246 = P[ (\dfrac{1}{20})^2 - 1]$

$246 = P[ (\dfrac{21}{20})^2 - 1 ]$

$246 = P[ \dfrac{441-400}{400}]$

$246 = P[\dfrac{41}{400}]$

$\dfrac{246 \times 400}{41} = P$

P = Rs2400

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

S.I. = ?

Time = 3 years

Rate = 6%

Formula to find S.I.

$S.I. = \dfrac{P \times R \times T}{100}$

Put the given values :-

$\dfrac{2400 \times 6 \times 3}{100}$

$Rs~ 432$

Answer => S.I. = Rs 432
