| 3) | 750 ft | 4) | 900 ft | 
| 5) | None of these | ||
Answer : 900 ft 
Explanation :
Explanation :
The circumference of the front wheel is 30 ft and that of the rear wheel is 36 feet.
Let, the rear wheel make n revolutions. At this time, the front wheel should have made n+5 revolutions.
	As both the wheels would have covered the same distance, 
        n x 36 = (n+5) x 30
	or 36n = 30n + 150
	or 6n = 150
	or n = 25.
	So, distance covered = 25 x 36 = 900 ft

 View Answer| Q426. | In a certain store, the profit is 250% of the cost. If the cost increases by 20% but the selling price remains constant, approximately what percentage of the selling price is the profit ? | 
| 1) | 55% | 2) | 60% | 
| 3) | 66.66% | 4) | 75% | 
| 5) | None of these | ||
Answer : 66.66% 
Explanation :
Explanation :
Let C.P.= Rs. 100. Then, Profit = Rs. 260, S.P. = Rs. 360.
	New C.P. = 120 % of Rs. 100 = Rs. 120
	New S.P. = Rs. 360.
	Profit = Rs. (360 - 120) = Rs.240.
	 Required percentage = (240/360) x 100 = 66.66%

| 3) | Rs. 600 | 4) | Rs. 800 | 
| 5) | None of these | ||
Answer : Rs. 500 
Explanation : P = Rs. 100
Explanation : P = Rs. 100
Given, R= 10% Time = 2 yrs 
So, C.I = Rs. 21  So,21 %  = 525 
100%  = (525/21) /100 = 2500
Then, P = (2500 x 5 x 4 ) /100 = Rs. 500

| 3) | 12% | 4) | 5% | 
| 5) | None of these | ||
Answer : 12% 
Explanation :
Explanation :
S.I. for 3 years = Rs. (12005 - 9800) = Rs. 2205.
S.I. for 5 years = [(2205/3 ) x 5 ]= Rs. 3675
Principal = Rs. (9800 - 3675) = Rs. 6125.
Hence, rate = [100 x 3675 /(6125 x 5 ) ] x 5 % = 12%
