Question

. Priyanka saves 60% of the money given by her father on her birthday and spends 25% on a doll,
which costs Rs 139.50. If her father gave 5% of his monthly salary to spend on the birthday, what
is the monthly salary of her father?​

Answer 1

Answer:

Let the monthly salary of Priyanka's father be Rs. “x”.

So, her father had given her = 5% of x = 5x/100 = x/20

She spends 25% of the money given, on a doll which costs = Rs. 139.50

According to the question, we can write,

[25% of (5% of x)] = Rs. 139.5

⇒ 25/100 * x/20 = 139.5

⇒ 0.25 * x * 0.05 = 139.5

⇒ x = 139.5 / 0.0125 = Rs. 11,160

Thus, the monthly salary of her father is Rs. 11,160.
