Answers with Solutions (6-10):
6. (2) Let CP = a, SP = 1.2 a
6. (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 – 0.94a = 264
0.24a = 264
a = 1100
7. (5) Govindamonthly expanses = 64000
Ratan’s monthly expenses = 64000 + 30% of 64000 = 83,200
Ramesh monthly expenses = 6 × 83,200 = 4, 99,200
Ramesh annual expenses = 59, 90,400 Rs
8. (2) Total number of teachers in school = 5200
Number of male teachers = 45% of 5200 = 2340
Number of male teachers who are less than 30 years = 30% of 2340 = 702
9. (4) Required amount = 40 × 14 + 16 × 44 + 12 × 300 + 14 × (14 + 40 + 28 = 560 + 704 + 3600 + 1148 = 6012
10. (1) Score of Sonia = 456 - 24 = 432
Let maximum marks be A, then 54% of A = 432
A = 800
Passing marks = 34% of 800 = 272
Required difference = 456 – 272 = 184
Ragini score = 184
