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."

Answer: Option B

Explanation:

Let the investments be A and (7200 - A) respectively.

Interest, I = P n r

Now, A × 1 × 4/100 = (7200 - A) × 1 × 5/100

or, 4A = 5×7200 - 5A

or, 5A + 4A = 36000

or, 9A = 36000

or, A = 4000

So, total income = A × 1 × 4/100 + (7200 - A) × 1 × 5/100

= 4000×4/100 + (7200 - 4000)×5/100 = 160 + 160 = 320 TK

1000 . A portion of the 7200 is invested at 4% annual return, while the remainder is invested at a 5% annual return. If the annual income from both portion is the same, what is the total income from the two investments?

A. Tk.166
B. Tk.320
C. Tk.400

Answer: Option C

Explanation:

Service charge for the 1st order = 75 tk (As the amount is less than Tk.2500)

Service charge for the 2nd order = 75 tk (As the amount is equal to TK.2500)

Service charge for the 3rd order = 100 tk (As the amount is more than Tk.2500)

Therefore, the total service charge = 75 + 75 + 100 = 250 tk

ans: 250 tk

Answer: Option A

Explanation:

If predator takes 2 leaps and prey takes 3 leaps to cover the same distance, then multiplying the distance by 2 you get predator 4 leaps and prey 6 leaps. With this ratio, they are covering the same distance with their respective leaps.

Therefore, they will always be the same distance away from each other unless either changes its speed.

so, ans: can't be determined.
