Answer: Option E

Explanation:

Let, Distance = D

we know that , T = D/s

Here, T = time, D = ddistance, S = speed

According to question,

D/6 + D/4 = 1

(2D + 3D) /12 = 1

D = 12/5

6 mile go 1 hours or 60 minutes

1 mile go 60/6 minutes

12/5 mile go ( 60×12)/ ( 6×5) = 24 minutes ( correct answer)

Answer: Option C

Explanation:

ধরি, করিমের convertible - এর mileage  =  100 
রহিমের convertible এর mileage  =  করিমের 40% বেশি

 =  140   +   21  =  161 
জলিলের hatchback - এর gas mileage করিমের চেয়ে (161  -  10O)  =  61% বেশি।

D. 120

View Answer	Favorite Question

Answer: Option B

Explanation:

Case 1: Rahim has three times as much money as Karim has.
let, karim's money = x, so rahim's money = 3x
Case 2: If Rahim gives Karim TK.50 then Karim will have three times as much money as Rahim will have.
After the condition - Rahim gives Karim TK.50
Karim's money = x + 50 & rahim's money = 3x - 50
After the condition - Karim will have three times as much money as Rahim will have,
karim's maney = 3 * rahim's money
or, x + 50 = 3(3x - 50)
or, x + 50 = 9x - 150
or, 8x = 200
so, x = 25
So, The money do they have together is: x + 3x = 4x = 4*25 = 100
Answer: 100

He needs to invest money in the inverse ratio of 8 %, 4% and 6%.

The ratio of money at 8% : money invested at 4% : money invested at 6% = 1/8: 1/4: 1/6

3:6:4

Sum of the ratios = 3+6+4=13

Money invested 4% SI = 6/13*2600=1200

Explanation:

Let total apple = x
