ANSWERS
1. (2)
Let CP = a, SP = 1.2 a
New CP = 0.8 a
New SP = 1.2 × 0.8 a = 0.96 a
1.2a – 0.96a = 264
0.24a = 264
a = 1100
2. (1)
Let Principal = P
Compound interest at 20% per annum for 2 years
= 44% of P (20 + 20 + 4)
44% of P = 880
P = 2000
Simple Interest for 4 years at 10% per annum = 40% of 2000 = 800
3. (5)
Govind’s monthly expanses = 64000
Ratan’s monthly expenses = 64000 + 30% of 64000
