A. 10%
B. 12.5%

D. 25%
E. None of these

View Answer	Favorite Question

Answer: Option B

Explanation:

Suppose cost price  =  100 Tk.
Gain on 25Tk  =  2.50 Tk  =  Selling price  =  25   +  2.50  =  27.50 TK 
Loss on 75 Tk  =  15 Tk Selling price  =  75  -  15  =  60 Tk 
Total selling price  =  60   +   27.50  =  87.50 
Loss  =  100  -  87.50  =  12.50

1041 . A person travels a certain distance at 3 km / hr and reaches 15 min late. If he travels at 4 km / hr, he reaches 15 min earlier . The distance he has to travel is __

A. 4.5km
B. 6 km
C. 7.2 km
D. 12 km

View Answer	Favorite Question

Answer: Option B

Explanation:

Let the time taken to travel at speeds 3 km/h and 4 km/h be t1 and t2 respectively.
So, t1 - t2 = 15 - ( - 15) = 30 minutes = 0.5 h
Now, let the distance travelled be = x km
So, (x / 3) - (x / 4) = 0.5
⇨ x = 6 km.

1044 . A person travels from P to Q at a speed of 40 kmph and returns by increasing his speed by 50%. What is the average speed for both the trips?

A. 36 kmph
B. 45 kmph
C. 48 kmph
D. 50 kmph

View Answer	Favorite Question

Answer: Option D

Explanation:

let, P to Q is x km. Thus he travels 2x km

1st Speed = 40kmph and 2nd speed will be = 40 + 40X50% = 60kmph

Now, time to go P to Q = x/40 and time to come from Q to P is = x/60 and total time taken = x/40 + x/60 = 5x/120 = x/24

Thus, Average speed = 2x/(x/24) = (24X2x)/x = 48kmph

Ans: Average Speed 48km/h

1048 . A pineapple costs Tk 7 and a watermelon costs Tk 5. Rahim spent exactly Tk 38 on these fruits. What was the number of pineapples purchased?

A. 2
B. 3
C. 4
D. Can not be calculated
E. None of these

View Answer	Favorite Question

Answer: Option C

Explanation:

"Rahim spent exactly 38 Tk on both type of fruits. If he bought only one watermelon and used the rest (38 - 5)  =  33 on pineapple, it would not be 'exact' as 33 can not be divided by 7 (the price of one pineapple)
2 watermelon, 4 pineapple  =  2  ×  5  +  4  ×  7  =  38 Tk
3 watermelon, 3 pineapple  =  3  ×  5  +  3  ×  7  =  36 Tk
So, only by buying 4 pineapples and 2 watermelon Rahim can spend exactly Tk 38."
