Question

Vikas spend 78% of his salary and save rupees 5550 find his salary

Answer 1

as we see that he used his 78 % of his salary so his left salary will be 100 - 78 = 22
$therefore \: 22\%ofx = 5550 \\ \\ = > x = \frac{22}{100} \times 5550 \\ \\ = >x = 1221$

therefore the total salary = 5550+1221= 6771
