Question : Out of 2500 people, only 60% have the saving habit. If 30% save with the bank, 32% with the post office, and the rest with shares, the number of shareholders is:
Option 1: 450
Option 2: 570
Option 3: 950
Option 4: 1250
Correct Answer: 570
Solution :
Total number of people = 2500
People who have saving habit is 60% = $\frac{60}{100}$ × 2500 = 1500
People who saves with bank is 30% = $\frac{30}{100}$ × 1500 = 450
People who saves with post office is 32% = $\frac{32}{100}$ × 1500 = 480
Remaining people who save with share = 1500 – 450 – 480 = 570
Hence, the correct answer is 570.
