Question

shakil has 2.73 , he has same number of 2p and 1p coins and there are only coins that he has , how many 1p coins does he has ?

Answer 1

2x+1x=2.73

3x=2.73

x=2.73/3

x=273/300

Answer 2

Let the number of 1p coins = x

Hence, we get,

0.01x + 0.02x = 2.73

( converting 1p to rs.)

0.03 x = 2.73

x = 91
