Answer 1

Number of 50 paise coins = Number of 20 paise coins.

Let number of 50 paise coins = x

According to the question,

0.2 x + 0.5x = 16.10

0.7x = 16.10

x = 16.10/0.7 = 23

Hence, there were 23 coins

Now,

She spent five 50 paise coins,

Coins left = 23 - 5 = 18

Hence,

$\bf{\red{There\:were\:18\:50p\:coins\\left\:after\:spending}}$
