**Solution:**

Dhruvika invested money for a period from May 2006 to April 2008 at a rate of 12% per annum. The interest received by her is ₹1620.

We have to find the money invested.

According to the question,

I = ₹1620

R = 12%

T = 2 years

We know, Interest I = P × R × T/100

1620 = P × 12 × 2/100

1620 = P × 12/50

1620 = P × 6/25

P = 1620 × (25/6)

= 170 × 25

= 6750

Therefore, the amount invested is ?6750.
