Ans: a

365 / 52 = 7 with remainder 1

365 days= 52 full weeks and extra day

∴ P(Monday) = 1/7

Ans : a

tan 60 =150/x

→ x = 150/√3

tan 45 = 150/(x+y)

→ x + y= 150

Solving, y = 150( 1 - 1/√3) 

∴ distance = 150( 1 - 1/√3) * 1/1000 km

time = 2/ 60 hour

Speed = distance / time

calculating, speed = 1.9 km/hr

Ans: e

tan θ = 3/4

Divide each term of the equation by Cos θ, you'll get:

(4 tan θ - 3) / (4  tan θ + 3)

substituting, you get 0

Ans: c

Actual New

r 1/2 .r

h   h

V(new) : Vol(actual)

= [1/3 π (1/2 .r)² . h] : [1/3 .pi π. r² . h]

= (1/2 .r)² : r²

=1 : 4

a) A true; R false

R: partly false Congruent shapes have both same shape AND SIZE.

equ 1: y=x/m + 3/m

equ 2: y= -2x/3 +7/3

Slope of perpendicular line: -1/(-2/3)= 3/2

Slopeof equ1: 3/2

Comparing: 3x/2 = x/m

Gives m=2/3

Ans: d : Both are false.

A) solving x=6, NOT 5.

R) Bisects; but not at right angles (unless it is a square)

Dividend% of NV = Return% of MV

15% of 40 = 12% of x

x = Rs 50
