Answer:

The rate of interest is 100%

Explanation:

Given: An amount of Rs. 1305 becomes Rs. 1740 in 4 months.

To find: Rate of interest

Solution:

We have, Principal amount, Amount, Time months or  years

P=RS 1305

A=RS 1740

S.I.=A-P=1740-1305=RS435

T=4 MONTHS = 4/12 YRS = 1/3 YRS

R% = ?

R% = 100×S.I./P×T

= 100×435×3/1305×1

= 100%

Hence, rate of interest is 100%
