Answer 2

Which of the following is an equation in a variable?

d) 3p = 12

3p = 12

∴ p = 12/4 = 3

Solve 3z = 9.

c) 3

9z = 3

∴ z = 9/3 = 3

If the age of Hari Kishan is 2 times the age of Manish (which is x years), then the age of Hari Kishan, in years, is

b) 2x

Manish age = x years

Hari Kishan age = 2 × x

∴ Hari Kishan's age = 2x

If Apala's present age is x years, what will be her age in years after 20 years from now?

a) x + 20

Solve: p + 1 = 2

a) 1

p + 1 = 2

= p + 1 - 1 = 2 - 1

= p = 2 - 1

= p = 1
