Question

Prerna decided to donate 30% of her monthly income to orphanages. But on the day of donation, she changed her mind and donated rs. 4200, which is 70% of what she had earlier decided. What should be her actual donation as per her earlier decision?

Answer 1

Answer:

20,0000

Step-by-step explanation:

let the initial amount she wanted to pay be x

70% of 30% of x = 4200

70/100 * 30/100 * x = 4200

2100/10000 * x = 4200

21/100 * x = 4200

x = 4200 * 100 / 21

x= 20000

Therefore, she had initially decided to pay 20,000

Answer 2

Answer:

6000

Step-by-step explanation:

70%(30%)x=4200

x=20000

actual donation=30%x=6000
