In a university, the number of students studying science, mathematics and language are in the ratio of 2:4:9. If the number of students in Science, Mathematics and Language be increased 10%, 20% and 40% respectively. What will be the new ratio ?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 11:24:63
Suppose the students studying science, mathematics and language are 20x, 40x and 90x respectively
If the number of students in Science, Mathematics and Language be increased 10%, 20% and 40% respectively then the new ratio will be
20x + 10% of 20x : 40x + 20% of 40x : 90x + 40% of 90x
20x + 2x : 40x + 8x : 90x + 36x
22x : 48x : 126x = 11 : 24 : 63
