Question

(1) Radhika's age is 6 years less than one-third of her mother's age. If mother's age is
86, find Radhika's age.
​

Answer 1

Let Radhika's age is $\large X$ years
And, Radhika's mother is 86 years old
According to question,

Rahika's age = (1/3 * Mother's age) - 6
Therefore,
$\large X$ = (1/3 * 86) - 6
$\large X$ = 86/3 - 6
$\large X$ = 68/3
$\large X$ = 22.67 years

Therefore, Radhika is 22.67 years old or 22 years and 8 months old (approx)
