Fill in the blanks.

S. No.	Principal (Rs)	Interest (Rs)	Amount (Rs)
(1)	1260	126	.......
(2)	1310	.......	1520
(3)	.......	632	1972

Answer 1

(1) Principal = Rs 1260
Interest = Rs 126
Amount = Principal + Interest
= Rs 1260 + Rs 126
= Rs 1386

(2) Principal = Rs 1310
Amount = Rs 1520
Amount = Principal + Interest
⇒ Interest = Amount – Principal
= Rs 1520 – Rs 1310
= Rs 210

(3) Interest = Rs 632
Amount = Rs 1972
Amount = Principal + Interest
⇒ Principal = Amount – Interest
= Rs 1972 – Rs 632
= Rs 1340
