**Solution:**

The difference of interest for 2 years and 3 years on a sum of ₹2100 at 8% per annum is _________.

We have to fill in the blanks to make the statement true.

__Interest__ = P × R × T/100

Given, P = ₹2100

R = 8%

For 2 years, I = 2100 × 8 × 2/100

= 21 × 16

= ₹336

For 3 years, I = 2100 × 8 × 3/100

= 21 × 24

= ₹504

Difference of interest = 504 - 336

= ₹168

Therefore, the required value is ₹168.
