Solution;
Given : 5p : 10p : 20p = 1 : 2 : 4
Amount of 5p coins = 1x
Amount of 10p coins = 2x
Amount of 20p coins = 4x
1x + 4x + 2x = 8400paise
7x = 8400
x = 1200
Amount of 10paise coins in the bag = 2 (x)
= 2 × 1200 = 2400 paise
No.of 10 paise coins = 2400/10 = 240
So, the correct option is D). None of these
