C. 600 kg
D. 640 kg

View Answer	Favorite Question

Answer: Option C

Explanation:

ধরি,

18% profit - এ বিক্রি করে x Kg

8% profit এ বিক্রি করে ( 1000 - x) Kg

(1000 - x) × 8/100 + x × 18/100 = 1000 এর 14/100

8000 - 8x + 18x = 14000

10x = 14000 - 8000

x = 6000/10

x = 600.

A. 2 kg
B. 4 kg

D. 6 kg

View Answer	Favorite Question

Answer: Option B

Explanation:

Amount of water in the mixture = 10% of 20 kg = 2 kg

So, amount of spirit = 20 - 2 = 18 kg

Percentage of spirit in new mixture = 100 - 25 = 75%

Now, 75% of mixture = 18 kg

So, 100% of mixture = 18 x 100 / 75 = 24 kg

So, amount of water need to be added = 24 - 20 = 4 kg

B. 12 minutes
C. 11 minutes
D. 21 minutes

View Answer	Favorite Question

Answer: Option D

Explanation:

Given,

On first minute monkey climb = 2 m

On the second minute it slips = 1 m

Calculation

On first minute monkey climb = 2 m

On the second minute it slips = 1 m

For every two minute,it climbs 1 m

So, average speed = 1 m/2 min

For 10 m, time is taken = 20 min

For the last 2 m jump add 1 min

So time taken = 20 + 1 = 21 min

∴ Monkey takes 21 minutes to reach the top of the pole.
