Question

1. Lata has got a 20% increment in her salary. After six
months she got another increment of 20%. What was
the net increase in Lata's salary?​

Answer 1

Step-by-step explanation:

let salary be X

20 × X + X = 1.2 X

100

20[1.2 X] + 1.2 X

100

0.2 [1.2X] +1.2 X

0.24X +1.2X

1.44X

1.44X ×100

X

144

so net increase is 44%
