 A) 8 B) 9 C) 10 D) 11

Explanation:

26 trees have 25 gaps between them,
Required distance (225/25) = 9

Q:

$\fn_jvn \sqrt[3]{9261} x \sqrt{62742241} = ? + 89$

Find the value of '?'

 A) 166251 B) 166259 C) 166252 D) 166253

Explanation:

Given $\fn_jvn \sqrt[3]{9261} x \sqrt{62742241} = ? + 89$

Using unit digit method,

On LHS,

1 x 1 x 1 = 1

sqrt of last digit 1 => it must end with either 9 or 1

so now

1 x 1 = 1

1 x 9 = 9

On RHS,

? + 89

=> ? = ...1 - 89 = last digit is 11- 9 = 2

or

=> ? = ...9 - 89 = last digit is 9 - 9 = 0

Here in the options last digit 2 is option C.

Q:

Given that 100.48 = x,  100.70 = y and xz = y2,  then the value of z is close to ___ ?

 A) 3.7 B) 2.7 C) 3.6 D) 2.9

Explanation:

xz = y2        10(0.48z) = 10(2 x 0.70) = 101.40

0.48z = 1.40

z = 140/18 = 35/12 = 2.9 (approx.)

Q:

What value will come in place of question mark (?) in the questions given below ?

[(180)2 ÷ 60×14] ÷ 9 = ? × 24

 A) 22 B) 33 C) 35 D) 28

Explanation:

Given

[(180)2 ÷ 60×14] ÷ 9 = ? × 24

[(180 x 180) ÷ 60×14] ÷ 9 = ? × 24

?= 180×3×14 / 9×24

? = 35.

Q:

The price of 2 oranges, 3 bananas and 4 apples is Rs. 15. The price of 3 oranges, 2 bananas and 1 apple is Rs. 10. What will be price of 4 oranges, 4 bananas and 4 apples  ?

 A) Rs. 10 B) Rs. 15 C) Rs. 20 D) Rs. 25

Explanation:

Let the Oranges be 'O', Bananas be 'B' and Apples be 'A'

From the given data,

2O + 3B + 4A = 15 ...... (I)

3O + 2B + A = 10 ..... (II)
