Question

Decrease $850$ in the ratio $17:6$ and then increase the result in the ratio $5:9$

Answer 1

Decrease in the ratio $=17:6$

Given quantity $=850$

Hence the decreased quantity can be calculated as given below

The decreased quantity $=\frac{6}{17}\times \text{given quantity}$

$=\frac{6}{17}\times 850$

$=300$

Now,

The quantity is increased in the ratio $5:9$

Therefore the final quantity can be calculated as given below

Final quantity $=\frac{9}{5}\times 300$

$=540$

Thus the final quantity is $540$.
