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
