Question

In an orchard, there are 156 chickoo trees in 6 rows. If all the rows have an equal number of trees, how many trees would there be in 15 such rows​

Answer 1

Answer: Total number of trees =48+60+96=204

Each of the trees are exactly divisible by 12, i.e. HCF of 48,60,96.

∴  

12

204

​

=17 rows are possible.

Answer 2

$Number \: of \: Chickoo \: \: tress \: \: in \: 6 \: rows : \: = 156$

$Number \: of \: Chickoo \: tress \: in \: 1 \: rows = \frac{156}{6} = 26$

$Number \: of \: Chickoo \: tress \: in \: 6 \: rows : 15 \: = 26 \times 15$

$= 390$
