**Answers:**

**Ans:1- 4**

Required total no. of promoted employees = 14% x 4000 x 25% + 35% x 22% x 4000

= 140 + 308

= 448

**Ans:2- 1**

Required difference = (44% x 4000 x 50% + 22% x 4000 x 35%) – (14% x 4000 x 75% + 20% x 4000 x 45%)

= 1188 – 780

= 408

**Ans:3- 3 **

Required ratio = [(22% x 35% + 44% x 50%) x 4000]:14% x 4000

= 297:140

**Ans:4-3**

The average number of un-promoted employees from all the four banks

= (1/4) x (44% x 50% + 22% x 65% + 14% x 75% + 20% x 45%) x 4000

= (1/4) x [2232]

= 558

**Ans:5- 5**

Number of promoted employees in Yes Bank and BOB together = (20% x 55% + 14% x 25%) x 4000

= 580

Total employees in BOI and SBI together = (22% + 44%) of 4000 = 2640

Therefore, Required % = (580/2640) x 100

= 22% approx

**Ans:6- 2 **

Required percentage = [(27% x 180,000 – 28% x 120,000)/(27% x 180,000)] x 100

= [(48600 – 33600)/48600] x 100

= (15000/48600) x 100

= 31% approx.

**Ans:7- 1**

Required difference = (27 + 14 + 8)% of 180 thousands – (31 + 16 + 6)% of 120 thousands

= (88.2 – 63.6) thousands = 24.6 thousands

**Ans:8-1**

Total no. of JBL earphones sold in U.P and Maharashtra together = 19% x 180 thousands

= 34.2 thousands

And that of Boat earphones in U.P and Maharashtra together = 19% x 120 thousands

= 22.8 thousands

Therefore, Required % = (34.2/22.8) x 100 = 150%

**Ans:9-3 **

Let selling price per item of Boat and JBL in M.P is 5x and 3x respectively. Since, here we know only profit of Boat earphones and we have no information about profit of JBL earphones.

So, answer can’t be found.

**Ans10:- 4**

Required average = (1/4) x (27 + 14 + 8 + 7)% x 180 thousands

= 25.2 thousands
