1. How much amount is required to be invested every year so as to accumulate ₹ 30,000 at the end of 10 years if the interest compounded annually at 10% Given A (10,0.1) = 15.9374.

(a) ₹ 1882.36

(b) ₹ 1828.30

(c) ₹ 1832.65

(d) ₹ 1853.65

**Answer : a**

A = 30,000

n = 10%

i= 0.1

A= P × A(n,i)

30,000 = P × A(10,i)

P = 30,000 / 15.9374

2. Suppose Mr. X invested 5,000 every year starting from today in mutual fund for next 10 years. Assuming that average return compounded annually is at 18% per annum. What is future value ?

(a) ₹ 1,83,677.68

(b) ₹ 1,38,678.85

(c) ₹ 1,83,776.53

(d) ₹ 1,38,774.55

**Answer : d**

A = 5,000

Period, n = 10 years

Future value = A / r × (1 + r) × [(1 + r)^{n} - 1]

= 5000 / 0.18 × (1.18) × [(1.18)^{10} -1]

= 5000 × 6.5555 × 4.233835

= 1,38,774.55

3. A person wants to open shop have two option to acquire a commercial space either by leasing for 10 years at annual rent ₹ 2,00,000 or by purchasing the space for ₹ 12,00,000. If person can borrow money at 14% compounded per annum. Which alternate is most suitable ? Given P (10,0.14) = 5.21611

(a) Leasing

(b) Purchase

(c) Can’t say

(d) Data insufficient

**Answer : a**

V = A × P (n,i)

= 2,00,000 × P(10,0.14)

= 2,00,000 × 5.21611

When is less than purchase price Hence, Leasing is preferable.

4. Find the 17^{th} term of an AP series is 15^{th}and 21^{st}terms are 30.5 and 39.5 respectively.

(a) 33.5

(b) 35.5

(c) 36.0

(d) 38.0

**Answer : a**

a) AP :

T_{15} = a + (15-1) d

30.5 = a + 14d

b) T_{21} = a + (21-1) d

39.5 = a + 20 d

30.5 = a + 14d

-39.5 = - a - 20d

-9 = -6d

1.5 = a

a : 30.5 = a +14 x 1.5

30.5 -21 = a

9.5 = a

c) T_{17} = a + (n-1)d

= 9.5 + (16) 1.5

= 33.5

5. In a survey of 100 boys it was found that 50 used white shirt 40 red and 30 blue. 20 were habituated in using both white and red shirts 15 both red and blue shirts and 10 blue and white shirts. Find the number of boys using all the colours.

(a) 20

(b) 25

(c) 30

(d) 35

**Answer : b**

Let A be the set of boys using white shirt,

Let B be the set of boys using red shirt,

Let C be the set of boys using blue shirt,

n(A) = 50, n(B) = 40, n(C) = 30, n(A ∩ B) = 20, n(B ∩ C) = 15, n(C ∩ A) = 10, we have to determine n(A ∩ B ∩ C).

Now n(A U B U C) = n(A) + n(B) + n(C) - n(A ∩ B) - n(B ∩ C) - n(C ∩ A) - n(A ∩ B ∩ C)

100 = 120 - 45 + n(A ∩ B ∩ C)

n(A ∩ B ∩ C) = 25.

6. In how many different ways can the letters of the word ‘ CORPORATION’ be arranged so that the vowels always come together?

(a) 810

(b) 1440

(c) 25200

(d) 50400

**Answer : **

7. If n^{th} terms of an AP series is 7n – 2, then sum of ‘n’ terms is :

(a) 0.5(7n^{2} + 2n)

(b) 0.5(7n^{2} - 3n)

(c) 0.5(7n^{2} + 2n)

(d) 0.5(7n^{2} - 2n)

**Answer : c**

n^{th} term = 7n – 2

go by option :

i)Option A :

S_{n} = 0.5 ( 7n^{2} + 2n )

n^{th} = 7n – 2

1^{st} term = 7 X 1-2 = 5

Put n – 1 in S_{n} = 0.5 (7n^{2} + 2n)

= 0.5 ( 7 X 1 + 2)

= 4.5

ii)key option c : S_{n}= 0.5 (7n^{2} + 3n)

n^{th} = 7n -2 n=1 1^{st} term = 5

S_{n} = 0.5(7 X 1 + 3)

S_{1 }= 0.5 X 10

= 5

Key n = 2

S_{2} = 0.5(7 X 4 + 3 X 2)

= 0.5 (28 + 6)

= 0.5 (34)

=17

1^{st} term = 5

2^{nd} term = 7n – 2 = n = 2

= 7 X 2 – 2

= 14 -2 = 12

S_{2} = 5 + 12 = 17

Thus ; option C is correct
