The marked price of a table is Rs 1500. If two successive discounts of 20% and 25% are given, what is the cost of the table to the shopkeeper?
(A) The shopkeeper's profit is 15% of the selling price.
(B) The shopkeeper's profit is 20% of the cost price.
Verify mobile number to view the solution
SP = 1500 x 80/100 x 75/100 = Rs 900
From (A)
Profit = 900 x 15/100 = 135
=> CP = Rs 765
From (B)
900 = 1.2 x CP
=> CP = Rs 750
Hence either statement alone is sufficient.
Average temperature of a week is 4°. What is the temperature on Wednesday?
A. Average temperature on Monday and Tuesday is 7° and average temperature from Thursday to Sunday is 3°
B. Average temperature from Wednesday to Sunday is 4° and average temperature from Monday to Wednesday is 3°
Total temperature of the week = 28°
Using statement A alone-
Total temperature from Monday to Tuesday = 14°
Total temperature from Thursday to Sunday = 12°
Temperature on Wednesday = 2°
Using statement B alone-
Total temperature from Monday to Wednesday = 9°
Total temperature from Wednesday to Sunday = 20°
Temperature on Wednesday = 1°
In the following questions a number of series are given. There may be a wrong term in each series. Find the wrong term in the following series.
12 38 100 298 892
The series is as following:
12x3-2=34,
34x3-2=100,
100x3-2-298,
298x3-2=892
What value will come in place of question mark (?) in the following questions?
72 x 25 + 45 x 20 = 153 - ?
1800 + 900 = 3375 - ?
=> ? = 3375 - 2700 = 675
18 x ? x 8 = 482 - 288
144 x ? = 2304 - 288 = 2016
? = 2016/144 = 14
172 + 113 + 122 + 83 = ?
? = 289 + 1331 + 144 + 512 = 2276
152 + 113 + 142 + 93 = ?
225 + 1331 + 196 + 729 = 2481
8.25 x 32 + 12.25 x 36 - 1.85 x 80 = ?
? = 264 + 441 - 148 = 557
28 x 19 + 12.5% of ? = 35% of 1800
532 + 12.5% of ? = 630
=> 12.5% of ? = 630 - 532 = 98
=> ? = 98 x 100/12.5 = 98 x 8 = 784
Find the wrong number in the following number series:
85, 148, 229, 328, 440, 580
The pattern is -
92+4=85,
122+4=148,
152+4=229,
182+4=328,
212+4=445,
242+4=580.
Hence the wrong term is 440
