Question

If Kishan's salary is 10% less than Baldev's salary,
then by what percentage is Baldev's salary more
than Kishan's salary?
(1) 11 1/9 %
(2) 10 %
(3) 11 2/9 %
(4) 11 3/4 %

Answer 1

let baldev salary be 100. then kishan salary will be 90.
percentage of kishan and baldev salary =10%

Answer 2

answer : option (1) 11 1/9%

explanation : Let baldev's salary = x

then, Kishan's salary = x - 10% of x

= x - 10x/100

= x - x/10

= 9x/10

= 0.9x

now we have to find percentage of salary of Baldev's salary more than Kishan's salary.

=( Baldev's salary - Kishan's salary)/Kishan's salary × 100

= (x - 0.9x)/0.9x × 100

= 0.1x/0.9x × 100

= 100/9 %

= 11 1/9 %

hence, option (1) is correct.
