Answer»

Let us assume money invested on scheme X, Y and Z be Rs. x, y and z respectively

Also assuming interest GAIN by Dharmesh from each scheme be α

We know the formula for simple Interest,

SI = (P × R × T)/100

Where,

SI = Simple Interest

P = Principle

R = Rate of Interest

t = Time period

∴ Interest gain from scheme X = (x × 4 × 7)/100 = α

⇒ x = 100α/28

Similarly Interest gain from scheme Y = (y × 6 × 4)/100 = α

⇒ y = 100α/24

And Interest gain from scheme Z = (z × 7 × 3)/100 = α

⇒ z = 100α/21

∴ x : y : z = 100α/28 : 100α/24 : 100α/21

We know that,

A : B : C = nA : nB : nC

Where n is a constant

∴ By MULTIPLYING Right hand side RATIO by 42/25 we GET,

⇒ x : y : z = 6 : 7 : 8
