repetitive GAT questions with the same numbers

Find the circumference of the circle below

a)3.14

b)31.4

C)314

d)6.28 cm

Correct answer: b)31.4

the diameter =10

the circumference of a circle =π•d

Circumference=3.14 X 10

so you move the decimal one place to the right

the circumference = 31.4

N is the midpoint of Ay, C is the midpoint of BD, Y is the midpoint of HA and D is the midpoint of GH then

A) 2/3

B) 3/5

C) 2/5

D) 1/5

Correct answer: A) 2/3

To answer these types of questions simply substitute the values of everything

Let’s say each distance is as this

so now we simply plug in the numbers

= 4(1)+2(2) / 4(2)+4(1)

= 4+4 / 8+4

= 8/12

= 2/3

In a two digit number, the tens digit is two more than the units, the sum of two digits multiplied by five then divide the product by 7 is 10, what is the number?

a) 75

b) 86

c) 68

d) 64

correct answer: C) 68

this is simply the case with some basic substitution

68

8+6=14

14×5=70

70÷7=10

A man has 120 of banknotes of 5 and ten SAR, a number paper 10 SAR is 5 times 5 SAR, what is the total amount?

A) 1300

B) 1100

C) 1200

D) 1000

Correct answer: B) 1100

Let’s use some variables

5x + x = 120

6x = 120

x=20

okay now let’s see how many 10 bank notes there are

5x = the number of 10 bank notes

5(20)=100 so there are 100 bills of 10 SAR

now let’s do the same thing for 5 bills

x= the number of 5 bank notes

X=20 so there are 20 bills of 5 SAR

then we multiply the number of bills by its amount

100 bills of 10 SR = 100 x 10 = 1000 SAR

20 bills of 5 SR = 20 x 5 = 100 SAR

now the total money

1000 + 100 =1100
