Question

A man has 25 paise and 20 paise coins total coins are 50 and amount is 11.25 .Make linear equation

Answer 1

Answer:

Let the no. of 20 paisa coins be X.

Then, the no. of 25 paisa coins will be (50-X).

ATQ,

20(X) + 25(50-X) = 11.25

20X + 1250 - 25X = 11.25

1250 - 5X = 11.25

- 5X = 11.25 - 1250

- 5X = - 1238.75

5X = 1238.75

X = 1238.75/5

X = 247.75
