Leakage সহ A ও B tank টি পূর্ণ করে ( 4 + 1/2) ঘন্টায় = 9/2 ঘন্টায়

Leakage 1 ঘন্টায় খালি করে ( 1/4 - 2/9) অংশ = 9 - 8 /36 = 1/36

Leakage দ্বারা tank টি খালি হয়. 36 ঘন্টায়

3574 . Two third of the faculty members of a department are female. Twelve of the male faculty members are unmarried, while 60% of them married. What is the total number of faculty members in the department?

A. 90
B. 60
C. 30
D. none of these

View Answer	Favorite Question	Report

Answer: Option A

Explanation:

Unmarried male faculty members are (100 - 60) = 40% of all male faculty members.

Now, 40% of male faculty = 12

So, Number of total male faculty members = 12 x 100 / 40 = 30.

Again, male faculty members are (1 - 2/3) = 1/3 of all faculty members.

Or, 1/3 of all faculty members = 30

So, number of total faculty members = 30 x 3 = 90.

3575 . Two trains 105 meters and 90 meters long, run at the speeds of 45 km/h and 72 km/h respectively , in opposite directions on parallel tracks. The time which they take to cross each other , is :

A. 8 seconds
B. 7 seconds
C. 5 seconds
D. 6 seconds

View Answer	Favorite Question	Report

Answer: Option D

Explanation:

Length of the 1st train = 105 m
Length of the 2nd train = 90 m
Relative speed of the trains,
= 45 + 72 = 117 kmph
= (117 × 5)/18
= 32.5 m/sec
Time taken to cross each other,
= (Length of 1st train + length of 2nd train)/ relative speed of the trains
∴ Time taken = 195/32.5
= 6 secs.
