Question

Dimple is five times as old as Simple. Five years from
now Dimple would be twice as old as Rimple. If Rimple
would be 30 years old after ten years, then find the
present age of simple.​

Answer 1

Answer:

Step-by-step explanation:

Answer is 7

Let Simple be S, Dimple be D and Rimple be R

5S=D

D+5=2R

R +10 = 30

D+5=40

D= 35

5S = 35

S= 5

Simple's age is 5

Answer 2

Answer:

Step-by-step explanation:

D=5S -----> [1]

After 5 years,

(D+5)=2(R+5)

D=2R+5 ------>[2]

After 10 years,

R+10=30

R=20

Substitute in [2],

D=45

S=45/5 =9

At present simple is 9 years old.
