Question
25% of the 66.67% of 75% of the 80% of any number is
6387. Find the value of 40% of that number.Solution
Let the number be x. ATQ- Let the number be x. Then we can translate the given information into the following equation: 0.25 × 0.6667 × 0.75 × 0.8 × x = 6387 Simplifying the left-hand side, we get: 0.25 x 0.6667 x 0.75 x 0.8 × x = (1/4) x (2/3) × (3/4) × (4/5) x x = 0.1x Substituting the given value of 0.1x in the equation, we get: 0.1x = 6387 Dividing both sides by 0.1, we get: x = 63870 Therefore, the number is 63870. To find 40% of this number, we can multiply it by 0.4: 40% of 63870 = 0.4 x 63870 =25548 Therefore, 40% of the number is 25548.
