Answer –**3. 75**

**Explanation :**

In the year 2013 = 2x: 3x: 4x

In the year 2014 = 3y:5y:7y

3y-5/5y-5 = ½

y = 5

Employees in 2014 = 15, 25, 35

Now 2x-n = 15

3x-n =25

x =10

Employees in 2013 = 20, 30, 40

No of left in 2014 = 3*5 = 15

**The cost of Coal block varies directly with the square of its weight. The Coal block is divided into three parts whose weights are in the ratio of 5:6:7. If the Coal block is divided into three equal parts by weight then there would be further loss of Rs.7200. Then what is the actual cost of Coal Block?**

1. 1166400

2. 2332880

3. 3888000

4. 3960000

5. None

###### Answer & Explanation

Answer –**1. 1166400**

**Explanation :**

Cost = (5x)2+(6x)2+(7x)2 = 110×2

When weights equal = (6x)2+(6x)2+(6x)2 =108×2

Loss = 7200 = 110×2-108×2=2×2

x =60

Actual cost = (6x+6x+6x)2

(18*60)2 = 1166400
