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. |
