A lift has the capacity of 18 adults or 30 children. How many children can board the lift with 12 adults?1. 62. 103. 124. 15

Answer» Correct Answer - Option 2 : 10

Given:

The capacity of the lift = 30 children or 18 adults

Calculation:

To find the capacity of the lift, find LCM of 18 and 30 = 90x

1 adult = 90x/18 = 5x

1 child = 90x /30 = 3x

If, the lift is occupied by 12 adults,

12 × 5x = 60x

Remaining capacity will be = 90x - 60x

= 30x

So, the number of children that be accommodated with 12 adults are:

30x/3x = 10

∴ 10 children can board the lift with 12 adults.
