Question

( If Sunita's age is 20% of Radha's age and Radha's age is 30% of Aamna's age, then what per cent of
Aamna's age is Sunita's age?​

Answer 1

Answer:

Let the Aamna's age be 100x

⇒ Radha's age = 30% of Aamna's age

⇒ Radha's age = 30/100 × 100x

⇒ Radha's age = 30 × x

⇒ Radha's age = 30x

⇒ Sunita's age = 20% of Radha's age

⇒ Sunita's age = 20/100 × 30x

⇒ Sunita's age = 2 × 3x

⇒ Sunita's age = 6x

⠀⠀⠀⠀⠀───────────────

• What percent of Aamna's age is Sunita's age :

⇢ Percent = Sunita / Aamna × 100

⇢ Percent = 6x / 100x × 100

⇢ Percent = 6x / x

⇢ Percent = 6%

∴ Sunita's age is 6% of Aamna's age.
