Step-by-step explanation:

Given:-

Rupees 45

To find:-

Divide 45 rupees in the ratio 3:5:7

Solution:-

Method-1:-

Given amount = Rs. 45

Given ratio = 3:5:7

Let they be Rs. 3X , Rs. 5X and Rs. 7X

Sum of the amount = 3X+5X+7X = 15X

=>15X = 45

=>X = 45/15

=>X = 3

3X = 3×3 = Rs. 9

5X = 5×3 = Rs. 15

7X = 7×3 = Rs. 21

The shares are Rs. 9 , Rs. 15 and Rs. 21

Method-2:-

Given amount = Rs. 45

Given ratio = 3:5:7

Total parts = 3+5+7 = 15

=> 15 parts = 45

=> 1 part = 45/15 =3

=>1 part = Rs. 3

3 parts = 3×3 = Rs. 9

5 parts = 5×3 = Rs. 15

7 parts = 7×3 = Rs. 21

The shares are Rs. 9 , Rs. 15 and Rs. 21

Answer:-

The shares are Rs. 9 , Rs. 15 and Rs. 21 for the given problem
