Question

Answer with solution​

Answer 1

Answer:

625

Step-by-step explanation:

20% of 40% of 1/5th of number.

Let number be x

% means 1/100

of means multiplication

So,

20/100 * 40/100 * 1/5 * x = 10

1/5 * 2/5 * 1/5 * x = 10

2/125 * x = 10

x = (125 * 10)/2 = 625

25% of 4 times of x = 25/100 * 4 * x = 1/4 * 4 * 625 = 625
