If the difference between 62% and 80% of a number is 198, then the difference between 92% and 56% of the number will be:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 396
The difference between two percentages of a number is itself a percentage of that number: 80% − 62% \(=18\%\), and 92% − 56% \(=36\%\).
18% of the number \(=198\)
36% is twice 18%, so 36% of the number \(=2\times198=396\)
The figure 1100 in Option (1) is the number itself (\(198\div0.18\)), not the difference asked for.
