2842 . Robin has 4 times as many marbles as Azad has and 5 times as many as Kalam has. If Kalam has more than 40 marbles, what is the least number of marbles Robin could have?

A. 200
B. 205
C. 210
D. 220
E. None of these

View Answer	Favorite Question	Report

Answer: Option D

Explanation:

let,

azad = a

robin = r

kalam = k

ATQ,

r = 4a = 5k

5k = 4a

k = 4a/5......i

again given k is more than 40

k>40

let k = 41

from equation... i

41 = 4a/5

a = 205/4 which is not integer

accordingly if k = 42, 43

a is not integer

but if k = 44

a = (44*5)/4

= 55

so minimum value of k is 44 for which minimum value of a is integer

r = 4a or r = 5k

r = 4*55 or r = 5*44

r = 220

ans: 220

Bangladesh Bank - Assistant Director - 2016

A. Ana
B. Ruby
C. Pamela
D. Rony

View Answer	Favorite Question	Report

Answer: Option D

Explanation:

Explanation : Ruby's height = 5'2"

Ana is taller than Ruby e.g. Ana's height > 5'2"
or we can write Ana's height = 5'2" + x

but Ana is not taller than Pamela.

So, height of Pamela > 5'2" + x

Let Pamela's height = (5'2" + x) + y

Pamela is shorter than her cousin Rony.

So, Rony's height > (5'2" + x) + y

here it is clear that, Rony is tallest because his height is greater than (5'2" + x) + y.

Hence, option (B) is correct.
