Answer 1

Answer:

18 years

Step-by-step explanation:

let smitha age be x

then manish age will be x-3

according to the question the ratio of

M ,l,n are 3:7:11

i.e.,there ages are 3y ,7y and 11y

manish age will be

x-3=3y

x=3y+3

now the average of smitha ,lata and neha is 22

i.e

3y+3+7y+11y whole divided by 3 =22

on simplification we get y=3

now calculate the present ages of manish,smitha and lata

i.e ,manish =9yrs

smitha =12yrs

lata=3 yrs

on average

9+12+33/3

=54/3

=18
