Question

Shyam had 30% of his money left after spending Rs. 280. How much did he have at first?

Answer 1

Let the total money he had be Rs x
According to question
x-280 = 30% of x
x-280 = 3x/10
10x-2800= 3x
10x-3x= 2800
7x = 2800
x = 400
He had Rs 400




Hope it helps!

Answer 2

He had 400 rs at first
