Answers:

Answer: (d)

A x60 /100=3B/4

A/B= 5/4

Answer: (a)

Let the CP be Rs.100.

SP = Rs.112

If the marked price be Rs.x, then 90% of x = 112

112x 100 x/90 = Rs. 1120/ 9

Required ratio 100: 1120 /9 = = 900: 1120 = 45: 56

Answer: (d)
Answer: (d)

Circumference = 2pi r

The decrease in area = – 50 – 50 + 50x 50/ 100 = –75%

Answer: (c)

Let the required number be x.( 7+x )/(11 +x )=3/4

28 + 4x = 33 + 3x

=>x = 33 – 28 = 5

Answer: (c)

Here, 20x + 5y = 3 => 5y = – 20x + 3

y = – 4x + 3/ 5

Slope of 20x + 5y = 3 => –4

We know, product of slopes = –1 for perpendicular lines

Hence, the slope of the line which passes through (–2, 5) and (6, b) =(b-5)/(6-(-2))

Now, =( b-5)/(6+2)= 1/4 => b – 5 = 2

b = 5 + 2 = 7

Answer: (b)

If the number of correct answers be x, then x × 4 – 1. (200 – x) = 200

=> 4x – 200 + x = 200

=> 5x = 400 => x = 400 5 = 80

Answer: (a)
Answer: (a)

Unit digit in 7⁴and3⁴=1

Therefore Unit digit in7³⁵ =Unit digit in( 7³²x 7³) = 1x7x7x7 =3

Unit digit in3⁷¹=Unit digit in (3⁶⁸ x 3³) =1x3x3x3=7

unit’s digit in the product 7³⁵ x 3⁷¹x 11⁵⁵=3x7x1=1

Answer: (d)

If the first divisor be a multiple of the second divisor, then required remainder = remainder obtained by dividing the first remainder (36) by the second divisor (17) = 2

17 is a factor of 136

Remainder when 36 is divided by 17 = 2
