Answer: Option A

Solution: (13056 ÷ 32)(513 ÷ 19) = ? + 95 \( \sqrt{1104 + 40 × 30} \)

408 x 27 = ? + 95 \( \sqrt{1104 + 200} \)

11016 = ? + 95 \( \sqrt{2304} \)

? = 11016 – 95 x 48

? = 11016 – 4560

? = 6456

2. \( \sqrt{29 × 1240 ÷ 31 + 173 × 5} \) × 36 =\( ?^2 \) + 29 × 16

    A. 32
    B. 33

Answer: Option E

Solution: \( \sqrt{29 × 1240 ÷ 31 + 173 × 5} \) × 36 =\( ?^2 \) + 29 × 16

\( \sqrt{29 × 40 + 865} \) × 36 = \( ?^2 \) + 464

\( \sqrt{1160 + 865} \) × 36 = \( ?^2 \) + 464

\( ?^2 \) = 45 x 36 – 464

\( ?^2 \) = 1620 – 464

\( ?^2 \) = 1156

\( ?^2 \) = \( \sqrt {1156}\)

\( ?^2 \) = 34

3. (16980 – 9910 – 4648) ÷ 14 = ? + (16650 ÷ 111)

    A. 23

Solution: 73% of 4936 + 24% of 5612 – 55% of 3848 = ?

\( \frac{73} {100}\) x 4936 + \( \frac{24} {100}\) x 5612 – \( \frac{55} {100} \) x 3848

? = 73 x 49.36 + 24 x 56.12 – 55 x 38.48

? = 3603.28 + 1346.88 – 2116.4

? = 4950.16 – 2116.4 = 2833.76

5. \( \frac{8} {13}\) – \( \frac{7} {26}\) x \( ?^2 \) = 234

    A. 25
    B. 26
    C. 27

Mensuration:

1. The breadth of a rectangle is equal to the diameter of a circle. The circumference of a circle is equal to the perimeter of a square of side 33m. What is the length of a rectangle. If the area of a rectangle is 756\( m^2 \)?

    A. 18m
    B. 19m
    C. 20m
    D. 17m
    E. 16m


Answer: Option A

Solution: According to the question,

Perimeter of a square = 4 × side

Perimeter of a square = 4 × 33 = 132m

Circumference of a circle 2πr

132 = 2 \( \frac{22} {7}\) × r

r = 21m

Diameter of a circle = 2r

Diameter of a circle = 2 × 21 = 42m

Breadth of a rectangle = 42m

Area of a rectangle = 756 \( m^2 \)

Area of a rectangle = Length of a rectangle × Breadth of a rectangle

Length of a rectangle = \( \frac{756} {42}\) = 18m

Compound Interest:

2. What will be the compound interest on a sum of Rs. 44,375 at compound interest compounded annually at 12% per annum in two years?

    A. Rs.11,288
    B. Rs.11,290
    C. Rs.11,289
    D. Rs.11,287
    E. Rs.11,291


Answer: Option C

Solution: According to the question,

P = Rs.44,375

r = 12%

t = 2 years

C.I = P({1 + \( \frac{r} {100})^t\) – 1}

C.I = 44375{(1 + \( \frac{12} {100})^2\)– 1}

C.I = 44375{( \( \frac{25 + 3} {25})^2\)– 1}

C.I = 44375{\( \frac{784 } {625}\) – 1}

C.I = 44375{\( \frac{784 – 625} {625}\)}

C.I = 44375 x \( \frac{159} {625}\)

C.I = 71 x 159 = Rs.11,289

3. 14 girls and 10 boys can do a piece of work in 5 days while 14 girls and 6 boys can do the same piece of work in 6 days. In how many days can 19 girls and 16 boys do the same piece of work?

    A. 3\( \frac{6} {7}\) days
    B. 3\( \frac{5} {7}\) days
    C. 3\( \frac{2} {7}\) days
    D. 3\( \frac{3} {7}\) days
    E. 3\( \frac{4} {7}\) days


Answer: Option D

Solution: 14 girls and 10 boys 1 day work

14 girls and 6 boys 1 day work

According to the question,

(14 girls + 10 boys) × 5 ≡ (14 girls + 6 boys) × 6

(70 girls + 50 boys) × 5 ≡ (84 girls + 36 boys) × 6

14 boys ≡ 14 girls

1 boy ≡ 1 girl

(19 girls + 50 boys) ≡ (19 girls + 16 boys) = 35 boys

M1 D1 = M2 D2

24 x 5 = 35 D2

D2 = \( \frac{5 × 24} {35}\)

D2 = 3\( \frac{3} {7}\)

(\( \frac{100 + 450} {100 + 300}\))\( \frac{x} {y}\) = \( \frac{4} {5}\)

The original fraction

(\( \frac{550} {400}\))\( \frac{x} {y}\) = \( \frac{4} {5}\)

(\( \frac{x} {y}\)) = \( \frac{4 × 8} {11 × 5 }\)

(\( \frac{x} {y}\)) = \( \frac{32} {55}\)

The original fraction = \( \frac{32} {55}\)
