Answer 1

Answer:

1052

Step-by-step explanation:

S.I. for 3 yrs=956-800=Rs.156

S.I. for 1 yr=Rs.52

Rate of interest=52 × 100/800=6.5%

If rate of interest is increased by 4%,

New rate= 6.5+4=10.5%

New Amount= 800+ 800×10.5×3/100=1052

Short tricks:

Rate of interest is increased by 4%

so,in 3 yrs it is increased by 3×4=12%

Increased Amount=12% of 800=96

New Amount=956+96=1052.
