Question : The pie chart given below shows the number of teachers in five universities. The total number of teachers in all these five universities is 720. The number of teachers in a particular university is shown in terms of degree with respect to the total number of teachers in all these five universities.
J1 = The value of the average number of teachers in B and C
J2 = The value of the average number of teachers in A and E
What is the value of (J2 + J1)?
Option 1: 210
Option 2: 290
Option 3: 250
Option 4: 240
Correct Answer: 290
Solution : The total number of teachers in all these five universities is 720.
J1 = The value of the average number of teachers in B and C
From the given pie- chart,
⇒ Number of teachers in University B $=\frac{30°}{360°}\times720=60$
⇒ Number of teachers in University C $=\frac{120°}{360°}\times720=240$
$\therefore$ Average $=\frac{60+240}{2}=150$
J2 = The value of the average number of teachers in A and E
⇒ Number of teachers in University A $=\frac{40°}{360°}\times720=80$
⇒ Number of teachers in University E $=\frac{100°}{360°}\times720=200$
$\therefore$ Average $=\frac{200+80}{2}=140$
So, J2 + J1 = 150 + 140 = 290
Hence, the correct answer is 290.
Question : Study the given table and answer the question that follows.
The table below shows the percentage distribution of students from five different colleges in various disciplines.
| DISCIPLINES | COLLEGES | ||||
| P | Q | R | S | T | |
| SCIENCE | 25 | 35 | 45 | 28 | 35 |
| ECONOMICS | 45 | 40 | 15 | 42 | 25 |
| MATHEMATICS | 30 | 25 | 40 | 30 | 40 |
|
TOTAL |
8000 | 10000 | 15000 | 9000 | 11000 |
Students from the discipline of mathematics in colleges P and R taken together is what percentage of the total number of students in colleges P and R taken together? [Give your answer correct to one decimal place.]
Option 1: 36.9%
Option 2: 36.5%
Option 3: 37.2%
Option 4: 37.5%
Correct Answer: 36.5%
Solution : Total students in P and R = Students in P + Students in R
= 8000 + 15000 = 23000
Students in Mathematics in P and R =
= 30% of 8000 + 40% of 15000
= 0.3 × 8000 + 0.4 × 15000
= 2400 + 6000 = 8400
Required percentage = $\frac{\text{Students in Mathematics in P and R}}{\text{Total students in P and R}}$×100%
= $\frac{\text{8400}}{\text{23000}}$×100%
= 36.5%
Hence, the correct answer is 36.5%.

Option 2: mild sweet due to low sulphur content
Option 3: less acidic
