Question

Vishal has only rs.2 and rs.5 coins. they add up to 57 in number and are worth rs.150. how many rs.5 are coins does he have?

Answer 1

12 coins

2x+5(57-x)=150

Answer 2

Let the number Rs 5 coins be x

The number of Rs 2 coins = ( 57 - x)

Their worth is Rs 150:

5x + 2(57 - x) = 150

5x + 114 - 2x = 150

3x = 150 - 114

3x = 36

x = 12

Find the number of Rs 5 coins

Rs 5 coins = x = 12

Answer: There are 12 Rs 5 coins.
