Solution:
Given, the ratio of 10p, 25p and Rs50p coins is 5:2:1 respectively.
Let the number of 10p, 25p and Rs50p coins be 5x, 2x and x respectively.
Total money in the bag = Rs.120
So, the value of the coins can be written as:
5x × 10p + 2x × 25p + x × Rs50p = Rs.120
Simplifying the above equation, we get:
50x + 50x + 50x = 12000
⇒ 150x = 12000
⇒ x = 80
Hence, the number of 10p, 25p and Rs50p coins are:
5x = 5 × 80 = 400
2x = 2 × 80 = 160
x = 80
Therefore, the number of 25p coins in the bag is 160, which is option A.
