In a locality the ratio of number of males and females is 7 : 6. If there are 1050 males, then what is the total population of the locality?
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → 1950
A ratio 7 : 6 means the population is made of equal parts: 7 parts males and 6 parts females, 13 parts in all. The number of males gives the size of one part.
One part \(=1050\div7=150\) (the 1050 males are 7 parts)
Total population \(=13\times150=1950\)
