(a) 16

(b) 17

(c) 18

(d) 19

The question was asked in an internship interview.

Asked question is from Applications of Linear Equation (Create and Solve the Equations) in chapter Linear Equations in One Variable of Mathematics – Class 8

Answer 1

The correct choice is (a) 16

Explanation: Let Ram’s present age be x years.

∴ Shyam’s present age will be 2x years.

After 10 years Shyam’s age would be, (2x + 10) years.

∴ Shyam’s age after 10 years = 2 * 3 + 10

∴ Shyam’s age after 10 years = 6 + 10

∴ Shyam’s age after 10 years = 16 years.
