KEY & SOLUTION

01. (C) Area of square = 4 × 16 sq. units = 64 units2

side of square = 64 units2 = 8 units

Perimeter of the given square = 4 × side = 32 units
02. (A) 895 × 312 = 279240
03. (D) 23 × 22 × 21 × ... × 4 × 3 × 2 × 1 = 23 × 22 × 21 × ... × 7 × 6 × 5 × 24
= 24 × 23 × 22 × 21 × ... × 7 × 6 × 5
04. (C) N and (N + 2) are always twin primes
∴ N (N + 2) + 1 is always a perfect square (OR)
3 × 5 + 1 = 15 + 1 = 16 = 42 which is a perfect square
11 × 13 + 1 = 143 + 1 = 144 = 122 which is a perfect square
05. (B) LHS = 1 + 2 – 3 – 4 + 5 + 6 – 7 – 8 + ... – 2012 + 2013

–4 –4
(–4) + (–4) ...... + (–4) + 2013

01. (B,C,D) LCM × HCF of the given two numbers = product of those two numbers
(HCF + LCM) of a & b a+b
(HCF – LCM) of a & b a–b
(HCF ÷ LCM) of a & b a÷b
02. (B,C) Perimeter of park = 4s = 4 × 95 m = 380 m
Distance covered for one round = 4 × 95 m = 380 m
Distance covered for 6 rounds = 6 × 4 × 95 m = 2280 m
03. (A,D) Option A and D are false statements
" "+! !
04. (A,B) < < is true
% %+" "
" % !
< < is true

03. (A) Krekin means work; blaf means force; drita means ground; and alti means place.
Drita means ground, so that rules out choices b and d. Choice c isn’t correct because blaf means force.
That leaves choice a as the only possible answer
04. (A) Brother of mother means maternal uncle. Hence only nephew of Aamir’s maternal uncle means Aamir
himself. Therefore Sonia is the wife of Aamir.
05. (B) Mahi, the docket is older than the policeman.
Since the doctor is younger than the Kavitha, Kavitha is not the policeman.
Hence Kavitha is the teacher.
