Solutions:
1. B) Mobile sale of company A = 65% of 48000 = 31200
Mobile sale of company B = 54% of 32000 = 17280
Total sale of mobiles (A + B) = 31200 + 17280 = 48480

2. A) Unsold Laptop by company B = 60000 × (100 – 57)/100 = 60000 × 43/100 = 25800
Refrigerator purchased by company B = 36000
Ratio = 25800/36000 = 43/60 = 43 : 60

3. B) Laptop = (54 – 48)/48 × 100 = 12.5% (rise)
Refrigerator = (40 – 54)/54 × 100 = -25.92% (fall)
AC = (48 – 40)/40 × 100 = 20% (rise)
Washing Machine = (76 – 48)/48 × 100 = 58.33% (rise)
Microwave = (51 – 76)/76 × 100 = -32.89% (fall)

4. A)  Refrigerator Sale of company B = 36000 × 72/100 = 25920
AC sale of company B = 54000 × 62/100 = 33480
Reqd % rise = (33480 – 25920)/25920 × 100 = 29.16 ≈ 29%

5. D) Total item sold = (48 × 0.65 + 54 × 0.52 + 40 × 0.67 + 48 × 0.56 + 76 × 0.78 + 51 × 0.48)
= (31.2 + 28.08 + 26.8 + 26.88 + 59.28 + 24.48) × 1000
= 196720

6. A) Total number of male (clerk + PO) students who applied in IBPS from Tamil Nadu
= 60% of 30% of 350 + 40% of 70 % of 350
= 63 + 98 = 161

7. D) Total number of students who applied in IBPS from Haryana = 400 × 150/100 = 600
Total number of students who applied in SBI from Haryana = 120 × 115/100 = 138
Now, total number of students who applied for PO in IBPS and SBI together from Punjab (or Haryana, as they are equal) = 400 × 65/100 + 120 × 25/1000 = 260 + 30 = 290
total number of students who applied for clerk in IBPS and SBI together from Haryana
Total applicants - PO applicants = (600 + 138) – 290 = 738 – 290 = 448

8. D) number of students who applied for PO from Assam in SBI
= 50% of 188 × 3/2 = 47 × 3 = 141
Number of students (PO + clerk) who applied in SBI from Assam
50% = 141
100% = 141 × 2 = 282

9. C) Reqd difference = (60% of 350 + 35% of 400) – (30% of 190 + 40% of 280)
= (120 + 140) – (57 + 112)
=350 – 169 = 181

10. A) Req. Avg. = (40% of 480 + 60% of 200 + 75% of 120)/3 = (192 + 120 + 90)/3 = 402/3 = 134
