Answers :
Direction (1-5) :
1) Answer: a)
(32/16)*(15/2) + 216 + 279 =?
15 + 216 + 279 =?
? = 510
2) Answer: d)
84 ÷ 642 × 5125 = 8x
84 ÷ 84 × 815 = 8x
84-4+15 = 8x
815 = 8x
x= 15
3) Answer: c)
(5x/3) – (2/3) * (12/17) * 3162 = (42/100) * 850
(5x/3) – 1488 = 357
(5x/3)Â = 1845
x = (1845*3)/5 = 1107
4) Answer: d)
25 % of x – 1664 ÷ 13 + 222 ÷ 6 = 67
(25/100)*x – 128 + 37 = 67
(25/100)*x = 67 + 128 -37
(25/100)*x = 158
x = (158*100)/25
x = 632
5) Answer: d)
√x × 13 – 26 % of 2650 – 12 × 28 = 15
√x × 13 – (26/100)*2650 – 336 = 15
√x × 13 – 689 – 336 = 15
√x × 13 = 15 +689 + 336
√x × 13 = 1040
√x = 1040/13 = 80
x = 802 = 6400
Direction (6-10) :
6) Answer: c)
The sales of gold in April and May = 28 + 14 = 42 lakhs
The sales of diamond in March and April = 13 + 7 = 20 lakhs
Required % = (42/20) × 100 = 210 %
7) Answer: b)
Difference between sales of gold and silver in all months together
= (12 + 15 + 22 + 28 + 14) – (30 + 18 + 42 + 36 + 28)
= 154 – 91 = 63 lakhs
Difference between sales of silver and diamond in all months together
= (30 + 18 + 42 + 36 + 28) – (18 + 9 + 13 + 7 + 14)
= 154 – 61 = 93 lakhs
Required % = (93 – 63)/93*100 = 32.25 % = 32 %
8) Answer: d)
The average number of platinum sold in all the given months together
= > (19 + 26 + 22 + 37 + 11)/5
= > 115/5
= > 23 lakhs
9) Answer: b)
Total platinum sold in April and may
= > 37 + 11 = 48 lakhs
Total silver sold in February and March
= > 18 + 42 = 60 lakhs
Required ratio = 48: 60 = 4: 5
10) Answer: b)
The difference between average of diamond and silver sold in all months
= > (154 – 61)/5 = 93/5
Average of silver sold in all the months =154/5
Required % = (93/154) × 100 = 60.38% = 60 % less
