Answer 1

Answer:

50 of 10 paise coins

Step-by-step explanation:

Let "x" the number of 10 paise coins, then "3x" is the number of 25 paise coins and (3x + 5) is the number of 50 paise coins.

0.1 x + 0.25(3x) + 0.5(3x + 5) = 120

(0.1 + 0.75 + 1.5)x + 2.5 = 120

2.35x = 120 - 2.5

2.35 x = 117.5

x = 117.5 ÷ 2.35

x = 50 coins  

Answer 2

Let the no. of 10 paise be x

then 25 paise is 3x

and 50 paise is 3x+5

convert all paise in rupees

then 1/4(3x)+1/10(x)+1/2(3x+5)=120

hence x=50

therefore 10 paise coin is 50
