Slot – 2 – Quantitative Aptitude – Arithmetic – Ratio and progression – In an examination, Rama’s score was one

Q. In an examination, Rama’s score was one-twelfth of the sum of the scores of Mohan and Anjali. After a review, the score of each of them increased by 6. The revised scores of Anjali, Mohan, and Rama were in the ratio 11:10:3. Then Anjali’s score exceeded Rama’s score by?
  1. 24
  2. 26
  3. 35
  4. 32
Answer: 32

Solution: Let score of Rama = r, mohan = m and Anjali = a
As score was one-twelfth of the sum of the scores of Mohan and Anjali.
So 12r = m + a……(1)
Similarly after score of each of them increased by 6, score of scores of Anjali, Mohan, and Rama
Becomes in the ratio 11 : 10 :3
Let 11k = r+6, m+6 = 10k and a+6 = 3k, putting values of the 3 in equation 1, we get
a – r = 40 – 8 = 32
