Answers:

1) Answer: B

Only 27, 57, 87 are two digit numbers which ends in 7 and are divisible by 3.

2)  Answer: D

√272.25+√2.7225+√0.027225

= 16.5 + 1.65 + 0.165

= 18.315

3)  Answer: A

The powers of 9 operate as follows

9¹ = 9

9² = 81

9³ = 729 and so on.

Hence, the power cycle of 9 also contains only 2 numbers 9 & 1, which appear in case of odd and even powers respectively.

So broadly these can be remembered in even and odd only, i.e. 4 odd = 4 and  4even = 6. Likewise

9odd=9 and 9 even =1

So,

29(136) =  9 even

So unit’s place = 1

4)  Answer: D

√((37+20√3) )–√(61+28√3)

√((5+2√3)2 )–√((7+2√3) 2)

= 5 + 2 √3 – 7 – 2√3

= – 2

5) Answer: B

I. (27)(1/3) > (13)(1/2) < (47)(1/6)

or (27)4 > (13)6 < (47)2

which is wrong.

II. (23)1/3 < (49)1/2 <  (52)1/6

Which is also wrong.

III. (53) 1/6 < (41)1/3< (37)1/2

or (53) < (41)2 < (37)3

which is right.

So option (b) is correct.

6)  Answer: B

P + Q + R – 36 days.

Efficiency of  P + Q + R = 6

R alone  can complete the work in =(36×6)/1= 216

7)  Answer: A

(A + B) for 5 hr = 10 × 5

= 50 unit

Remain = 10 unit

A + B – C= 5/hr

Total time in which tank will be filled

=10/5+5 hr

= 7 hr

8)  Answer: C

Discount= a+b-  ab/100

= 40+20-(40×20)/100

= 52%

9)  Answer: D

Let M.P. = x

M.P.×((100 –Discount)/100)%=S.P.

x×((100 –35)/100)%=2275

x× 65/100=2275

x = 3500 Rs.

10)  Answer: A

P : Q : R= 1/2  :  1/3  :  1/12

or  6 : 4 : 1

given 11R = 121000

1R = 11000

Q’s share = 4R

= 4 × 11000

= 44000
