Hi Ashutosh,

In such type of questions, firstly we take the first two numbers and cross multiply them. The numerator of first number when multiplied by denominator of second number (5 x 11 = 55) gives the value of first number and the numerator of second number when multiplied by denominator of first number (9 x 7 = 63) gives the value of second number. Thus, 5/7 is smaller than 9/11. Similarly, when second
and third numbers are compared, then the value of second number is (9 x 8 = 72) and the value of third number is ( 7 x 11 = 77).
Thus, we got the answer.

Hope you understood it.
