What will come in place of the question mark (?) in the following sequence?
125 × 24 + 60% of 660 = 4 × ?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 849
The left side is worked out first: the product, then the percentage, then their sum. The right side is 4 times the missing number, so dividing the left side by 4 gives it.
The product: \(125\times24=3000\)
The percentage: 60% of 660 \(\displaystyle=\frac{60}{100}\times660=396\)
The left side: \(3000+396=3396\), which equals \(4\times ?\)
The missing number: \(\displaystyle\frac{3396}{4}=849\)
