A. 5%
B. 12%
C. 15%

Answer: Option A

Explanation:

Interest in 2 years=500-460=40 taka

So, Interestper year=40/2=20 taka

So, Principal=460-(3×20)=400 taka

So, r=(I/pn)×100%

=(20/400)×100%

=(1/20)×100%

=5%

Three Combined Bank Recruitment - Senior Officer 03 .08.2018 ||

A. 18%
B. 15%
C. 26%
D. 5%

View Answer	Favorite Question

Answer: Option D

Explanation:

(5 - 3) = 2 years interest = (500 - 460) = 40 tk

1 years interest = 40/2 = 20 tk

3 year's interest 20 × 3 = 60 tk

Principle amount = (460 - 60) = 400 tk

Interest rate = (60×100)/(400×3) = 5% (ans).

then the age of other children ( x + 3) , (x + 6), (x + 9), (x + 12)

Then, x + (x + 3) + (x + 6) + (x + 9) + (x + 12) = 50

5x = 20

x = 4

D. 45

View Answer	Favorite Question

Answer: Option B

Explanation:

Let,

Son = x years

Then, Father = (80-x) years

10 years ago,

Son was = (x-10) years

Father was = (80-x-10) = (70-x) years

ATQ,

70-x = 3(x-10)

=> 70-x = 3x-30

=> 4x = 100

=> x = 100÷4 = 25 years

So, Son is 25 years old.

Ans. 25

A. 12 years
B. 14 years
C. 18 years
D. 20 years

View Answer	Favorite Question

Answer: Option D

Explanation:

Let the present ages of son and father be x and (60 - x) years respectively.
Then, (60 - x) - 6 = 5(x - 6)
⇒ 54 - x = 5x - 30
⇒ 6x = 84
⇒ x = 14
∴ Son's age after 6 years = (x + 6) = 20 years.
