Question
Nancy donated 20% of her salary in charity, and deposited 40% of the remaining salary in the bank. Now she’s left with Rs 7000. What was her original salary?
Solution
Sure, let's solve this step by step:
-
Let's assume Nancy's original salary was Rs X.
-
She donated 20% of her salary to charity, which means she was left with 80% of her salary. Mathematically, this can be represented as 0.8X.
-
Nancy then deposited 40% of the remaining salary (0.8X) in the bank. So, she was left with 60% of 0.8X, which can be represented as 0.6 * 0.8X = 0.48X.
-
According to the problem, 0.48X equals Rs 7000.
-
To find the value of X (Nancy's original salary), we can divide 7000 by 0.48.
-
X = 7000 / 0.48 = Rs 14583.33
So, Nancy's original salary was approximately Rs 14583.33.
