Arithmetic Operation 3 / 10 Six years ago, the ratio of the ages of Kunal and Sagar was 6 : 5. Four years hence, the ratio of their ages will be 11 : 10. What is Sagar's age at present? 12 16 18 24 Oops! Your answer is wrong. Wow! Your answer is correct. Explanation:Let the ages of Kunal and Sagar 6 years ago be 6x and 5x years respectively.Then, {(6x + 6) + 4}/ {(5x + 6) + 4} = 11/10⇒ 10(6x + 10) = 11(5x + 10)⇒ 5x = 10⇒ x = 2∴ Sagar's present age = (5x + 6) = 16 years. Arithmetic Operation 4 / 10 Currently, Andrei is three times Nicolas' age. In ten years, Andrei will be twelve years older than Nicolas. What are Nicolas's ages now? 4 years 6 years 10 years 8 years Oops! Your answer is wrong. Wow! Your answer is correct. Explanation:Let, the current Nicholas age be x and Andrei age be 3x.According To Question,3x + 10 = x + 10 + 12Or, 2x = 12Or, x = 6Therefore, the current Nicholas age 6 years.

Your answer is correct. Explanation:Let the son's present age be x years.Then, man's present age = (x + 24) yearsAccording to question,(x + 24) + 2 = 2(x + 2)or, x + 26 = 2x + 4or, x = 22 Arithmetic Operation 6 / 10 The present age of Jacob’s father is three times that of Jacob. After 5 years, the sum of their ages would be 70 years. Find Father's present ages. 48 72 54 45 Oops! Your answer is wrong. Wow! Your answer is correct.

(ii)Using (i) in (ii),⇒ x + 10 + 3x = 70⇒ 4x = 60⇒ x = 15Putting x = 15 in (i), we get y = 45.Therefore, the age of Jacob is 15 years and Jacob's father is 45 years. Arithmetic Operation 7 / 10 Tom’s mother’s age is 5 years more than the three times Tom’s present age. Find Tom’s present age, if his mother is 44 years old. 16 years 13 years 24 years 26 years Oops!
