Answer 1

The answer is 64.

Solution:

Assume the number of 1 rupees coin is said as x.

Then the number of 50 paise is 4x.

Number of 25 ps is 2x

The box contains 56 rupees ie 5600ps

Therefore equation is 100x + (50 * 4x) + (25 * 2x) = 5600

100x + 200x + 50x = 5600

350x = 5600

x = 5600/350

x = 16

Number of 50 paise coin is 4x = 16 * 4 = 64.

The answer is 64.
