Answer:

This is a question about simple interest.

Step-by-step explanation:

SI = P * R * T / 100, where P is principal, R is rate and T is time in years, and SI is simple interest.

Here, the principal (800 Rs.), time in years (3 years), and the simple interest (956 - 800 = 156 Rs.) is given.

SI = P * R * T / 100

= 156 = 800 * R * 3 / 100

= 156 = 8 * R * 3

= 156 = 24 * R

= 156 / 24 = R

= R = 6.5%

If Rate is increased by 4%,:

SI = P * R * T / 100

= SI = 800 * 10.5 * 3 / 100

= SI = 8 * 10.5 * 3

= SI = 252 (And the amount is 800 + 252 = 1052)
