Solve this
A box contain coin of 5 and 10
And their ratio is 5 : 2
And their sum is 135 rupee find the
Value of 5 and 10 rupee coin

Answer 1

Solution :

Assuming the ratios of coin 'y'

Given -

The numbers of ₹5 coins = 5

Hence ,

It's Value = 5 × 5 = ₹25

The numbers of ₹10 coins = 2

Hence ,

It's Value = 10 × 2 = ₹20

Now ,

Sum of (25 + 20)y = 135

➨ ( 25 + 20 )y = 135

➨ 45y = 135

➨ y = 135/45 = 3

Here , we have the value of y i.e. 3.

Now ,

➨ 25y = 25 × 3 = ₹75

➨ 20y = 20 × 3 = ₹60
