**The number of students in 3 classes is in the ratio 2 : 3 : 4. If 12 students are increased in each class this ratio changes to 8 : 11 : 14. The total number of students in the 3 classes in the beginning was:**

A. 108**B. 162**

C. 96

D. 54

**Municipal Officer (Civil) Local Govt-21**

Let the number of students in the classes be 2x, 3x and 4x.

Total students = 2x + 3x + 4x = 9x

According to the question,

2x + 12 / 3x + 12 = 8 / 11

24x + 96 = 22x + 132

x = 18

Hence, original number of students,

9x = 9 x 18

x = 162

**In a mixture of 60 litres, the ratio of milk and water is 2:1. If this ratio is to be 1:2, then the quantity of water to be further added is:**

A. 56

B. 50**C. 60**

D. 70

**PMS (P) Ministerial Quota GK-19/Tehsildar Paper II-20 (E)**

Quantity of milk = (60 x 2/3) litres = 40 litres

Quantity of water = (60 – 40) litres = 20 litres

New ratio = 1:2

Let the quantity of water to be added further be x litres

Then milk:water = (40/20+x)

Now, 1/2 = (40/20+x)

=> 20 + x = 80

=> x = 60

∴ Quantity of water to be added = 60 litres

A. 4/3

B. 2/5**C. 3**

D. 6

**Asst PDMA BOR-21**

a+b = √5+1 / √5-1 + √5-1 / √5+1

a+b = (√5+1)^{2} + (√5-1)^{2} / (√5-1)(√5+1)

a+b = (√5+1)^{2} + (√5-1)^{2} / (√5)^{2}-(1)^{2}

a+b = (√5+1)^{2} + (√5-1)^{2} / 5-1

a+b = (√5+1)^{2} + (√5-1)^{2} / 4

a+b = 5+1+2√5+5+1-2√5 / 4

A. 12

B. 13**C. 14**

D. 15

**Asst S&GAD-20**

Let the two numbers be x and y

(x^{2} + y^{2}) = 100 . . . (i)

(x^{2} – y^{2}) = 28 . . . (ii)

Adding both the equations

x^{2} + x^{2} + y^{2} – y^{2} = 100 + 28

2x^{2} = 128

x^{2} = 128 / 2

x^{2} = 64

x = 8

Put the value of x in one of the above equations to calculate the value of y.

Hence y = 6

Sum of both numbers = 6 + 8 = 14
