Answers:
1.Answer: D
250% of 150 + 35% of 500 – 350 = x – 450
375 + 175 – 350 = x – 450
375 + 175 – 350 + 450 = x
X = 250
2.Answer: a
Let the original fraction be x/y
(350/50)(x/y)=7/5
x/y= 1/5
3.Answer: B
X + y = 8000 ——- (1)
(x/100)*125 + (y/100)*85 = 8000
(25/20)x + (17/20)y= 8000
25x + 17y = 8000*20= 160000 ——- (2)
Solve this equation (1) & (2)
X= 3000
Y= 5000
4.Answer: B
52+1 =25 + 1 = 26
102+1 = 101
152+1 = 226
202+1 = 401
252+1= 626
302 + 1 = 901
5.Answer: C
(x+y)2 = x2+y2+2xy
(x+y)2 = 81 +(2.(-40))
= 81 – 80
(x+y)2 =1 = 1
6.Answer: A
(tan 1°. tan 89°) (tan 2°. tan 88°) ………. tan 45°
(tan 1°. cot 1°)(tan 2° cot 2°) ……….. tan 45°
Tan 45° =1 ∴[tanθ.cotθ = 1]
7.Answer: B
Every triangle has exactly three medians, one from each vertex, and they all intersect each other at the triangle’s centroid. In the case of isosceles and equilateral triangles, a median bisects any angle at a vertex whose two adjacent sides are equal in length.
8.Answer: B
A+B = 1/15
B+C = 1/12
C+A = 1/10
2(A+B+C) = 1/15 + 1/12 + 1/10 = 15/60 = 1/4
ABC = 2/4 = 1/2
A ,B and C can finish the work in 2 days
9.Answer: C
(5×30) – (28×4) = 150 – 112 = 38
10.Answer: D
307 = (3×5×2)7 = 37×57×27
225= (11×2)5 = (25×115)
3412 = (2×17)12 = (212×1712)
125 = (2×2×4)5 = (25×25×45)
=2 (7+5+12+5+5)× 115×1712×312×57 = 234× 115×1712×312×57
Required number of prime factors 34+5+12+7+12= 70
