Question

a man has only 20 paise coins 25 paise coins in his purse if he has 50 coins on totalling Rs 11.25 how many coins of each does he have​

Answer 1

Answer:

Let no. of 20 paise coins is x and no. of 25 paise coins is y. Then by the given question,

x+y=50 --------------------(1) and

20x+25y=1125 [∵, Rs. 11.25=1125 paise]

or, 4x+5y=225 -----------(2)

Multiplying (1) with 4 we get,

4x+4y=200 ---------------(3)

Subtracting (3) from (2) we get,

y=25

Putting in (1)

x=50-y=50-25=25

∴, x=25, y=25
