The data given in the table shows the number of students studying in 4 different disciplines in 5 institutes. Study the table and answer the question: Institutes Arts Science Commerce Computer Science A 36 48 59 57 B 45 54 55 48 C 55 36 56 51 D 45 48 55 53 E 48 44 52 55 What is the ratio of number of students studying Science in institutes C and D taken together to the number of students studying Computer Science in institutes A and E taken together? Correct Answer 3 ∶ 4 Number of students studying Science in Institute C = 36 Number of students studying Science in Institute D = 48 Total number of students studying Science in Institute C & D = (36 + 48) = 84 Number of students studying Computer Science in Institute A = 57 Number of students studying Computer Science in Institute E = 55 Number of students studying Computer Science in Institute A & E = (57 + 55) = 112 Now, The ratio of number of students studying Science in institutes C and D taken together to the number of students studying Computer Science in institutes A and E taken together ⇒ 84 : 112 ⇒ 3 : 4 ∴ The ratio of the number of students studying Science in institutes C and D taken together to the number of students studying Computer Science in institutes A and E taken together is 3 : 4.
