Answer :
1. 3;
From statement I;
From statement II;
2. 5;
From both statement I and statement II;
Rahul = 4x; Trisha = 3x
⇒ 16x + 32 = 15x + 40
∴ x = 8
Rahul's age = 32 years
∴ Deepak's age =
∴ Rahul's wife 's age = 36 - 8 = 28 years
3. 5;
4. 1;
From statement I;
Ratio of Sumrita, Sushil and Shilpa
= 12 x 5 : 12 x 6 : 6 x 6 = 5 : 6 : 3
Now, 43% = 25585

∴ Share of Shilpa = 3/14 x 59500 = Rs, 12750
5. 5;
From both statement I and statement II;
5C+ 3T = 6220 ....(i)
and C - T - 420 ....(ii)
Solving (i) and (ii)
5T - 2100 + 3T = 6220
8T = 8320 , IT, Rs. 1040, IC = Rs. 620
Cost of OB = 3C + 2T = 1860 + 2080 = Rs. 3940
∴ Required answer = 2B + 4C + 3T = Rs. 13480
