Question

Sitha davi has Rs 9 in 50 pasia and 25 paisa in coin she as twice as many 25paisa coin, how many coin of each kind does she has​

Answer 1

Answer:

Let no. of 50 paisa coins be x, then no. of 50 paisa coins will be 2x.

So, 9 Rs. = 900 paisa.

900 = 50x + 25 *2x

900 = 50x + 50x

900 = 100x

x = 9

So, no. of 50 paisa coin = 9 and no. of 25 paisa coin = 2x = 18.
