Question

A shopkeeper had some chairs. He sells 40% chairs and still has 420 chairs. Originally he had,
1. 588 chairs
2. 600 chairs
3. 672 chairs
4. 700 chairs

Answer 1

Correct Answer - Option 4 : 700 chairs

Suppose originally he had x apples.

Then, (100 - 40)% of x = 420

\(\Rightarrow \frac{{60}}{{100}} \times x = 420\)

\(\Rightarrow x = \frac{{420 \times 100}}{{60}} = 700\)
