Q:

In a class of 80 students and 5 teachers, each student got shopping coupons that are 15% of the total number of students and each teacher got shopping coupons, that are 25% of the total number of students. How many shopping coupons were there?

A) 960 B) 1000
C) 1060 D) 100
 
Answer & Explanation Answer: C) 1060

Explanation:

Given total number of students = 80

Total teachers = 5

Number of coupons each student got = 15 x 80/100 = 12

Number of coupons each teacher got = 25 x 80/100 = 20

 

Therefore, total number of shopping coupons = 80 x 12 + 5 x 20 = 960 + 100 = 1060.

Which of the following chemical compounds has the highest boiling point?

A) Dimethyl ether (CH3OCH3) B) Methanol (CH3OH)
C) Methane (CH4) D) None
 
Answer & Explanation Answer: B) Methanol (CH3OH)

Explanation:

Chemical Compounds with stronger intermolecular forces have higher boiling points.

 

The order of strengths of intermolecular forces is:

 London dispersion < dipole-dipole < H-bonding

 

Methane (CH4) — London dispersion forces

Dimethyl ether (CH3OCH3) — dipole-dipole attractions

Methanol (CH3OH) — hydrogen bonding

Therefore, Methanol - CH3OH with H-Bonding have highest Boiling Point among the given chemical compounds.

Q:

The sum of the present ages of a father and his son is 70 years. Five years ago, father's age was 5 times the age of the son, so now the son's age will be?

A) 12 B) 14
C) 15 D) 19
 
Answer & Explanation Answer: C) 15

Explanation:

                                                               Father           Son

 

5years ago the age of the father & son           5X                X

 

present the age of the father & son              5X+5             X+5

 

(present age of father) + (present age of son) = 70

 

       (5x+5)                 +        (x+5)              = 70

 

 Then you will get X = 10

 

Present age of the son (x+5) = 15
