Total number of students from IIT = 23700
(A) How many employees of TATA and Birla are students from IIT?
(B) How many employees of Reliance and Satyam are students from IIT?

• A. (A) $\to$ 4641; (B) $\to$ 5956
• B. (A) $\to$ 3822; (B) $\to$ 8242
• C. (A) $\to$ 8643; (B) $\to$ 2525
• D. (A) $\to$ 7347; (B) $\to$ 6399

Answer 1

The correct option is D

(A) $\to$ 7347; (B) $\to$ 6399

(A) Total number of students from IIT = 23700

Percentage of students working in TATA $=17\%$
Percentage of student working in BIRLA $=14\%$
$\therefore$ Number of students from IIT working in TATA and BIRLA \(=\frac{(17+14)}{100} \times 23700\)
$=\frac{31}{100}\times 23700=7347$

(B) Percentage of students working in Satyam $=12\%$
Percentage of students working in Reliance $=15\%$
$\therefore$ Number of students from IIT working in Satyam and Reliance $=\frac{(15+12)}{100}\times 23700$
$=\frac{27}{100}\times 23700=6399$
