Question

A jet had passengers up to 90% of its capacity how many passengers was the jet carrying, its capacity was 130 passengers ?​

Answer 1

Let the jet is carrying X passengers currently.

$\frac{x}{130} \times 100 = 90 \\ \frac{x}{130} = \frac{90}{100} \\ x = \frac{130 \times 90}{100} \\ x = 13 \times 9 = 117$

Hence the jet is 117 passengers currently.
