Question

A box contain x 50-paise coins, 2x one rupees coins and 3x two rupees coins. If the total value of thes coins is Rs 68, what the value of x ?

Answer 1

Hi ,

Number of 50 paise coins = x

number of 1 Rs coins = 2x

number of Rs 2 coins = 3x

Total value of the coins = Rs68

Rs1/2 × x + Rs1 × 2x + Rs2 × 3x =Rs 68

x /2 + 2x + 6x = 68

x /2 + 8x = 6

( x + 16x )/2 = 68

17x = 68 × 2

x = ( 68 × 2 ) / 17

x = 4 × 2

x = 8

Therefore ,

The value of x = 8

I hope this helps you.

Answer 2

Num of 50 paise coins = x

num of 1 Rs coins = 2x

num of Rs 2 coins = 3x

Total coins = Rs68

Rs1/2 × x + Rs1 × 2x + Rs2 × 3x =Rs 68

x /2 + 2x + 6x = 68

x /2 + 8x = 6

( x + 16x )/2 = 68

17x = 68 × 2

x = ( 68 × 2 ) / 17

x = 4 × 2

x = 8
