Question

A man has only 80 paise coins and 50 paise coins in his purse .If he has 50 coins in all totally rs 11.25 .How many coins of each kind does 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
