There are 361 saplings of Mango and Neem in a garden. The ratio of the number of Mango saplings to that of Neem saplings is 8 : 11. How many Neem saplings are there in the garden? Correct Answer 209

Trick:

Neem saplings = 361 × 11/19 = 209

Detailed solution:

Let the number of Neem saplings be x.

⇒ The number of Mango saplings = 361 – x

The ratio of the number of Mango saplings to that of Neem saplings is 8 : 11,

⇒ (361 – x) /x = 8/11

⇒ 11(361 – x) = 8x

⇒ 3971 – 11x = 8x

⇒ 3971 = 19x

∴ x = 209
