Answers :
Direction (1-4) :
1) Answer: a)
This graph clearly shows that the increase in income March to May.
2) Answer: b)
March is more than the month of February
3) Answer: a)
4) Answer: c)
5) Answer: b)
The cost of the article after the first rebate =65 – 6.5 = 5.5
Therefore, second discount
6) Answer: c)
Since interest is collected half yearly on R% per year, the value will be lower than the value of R (Remember, half yearly compounding is always beneficial for the depositor)
7) Answer: b)Â Â Â Â Â Â Â Â Â Â Â Â Â
8) Answer: c)
9) Answer: b)
Given, OAB is an equilateral triangle and is the midpoint of the circumcircle of the equal angle.
10) Answer :c)
If α and β are the roots of equation x² + 6x + 1 = 0
∴ α and β = − 6 & αβ = 1
Now, (α – β) 2 = (α + β) 2 – 4 αβ
= (-6)² – 4
= 36 – 4 = 32
11) Answer: c)
The sum of all even two digit numbers
= 10 + 12 + 14 + …. + 98
= 2(5 + 6 + 7 + …. + 49)
The divisor must be 18, 36 or 54 as it is one of them. It must be 54 for when 54 × 45 is divided by 54, the quotient is 45 and in these, the digits are reversed. So, the divisor must be 54
12) Answer: b)
13) Answer: a)
Method I
Iet we will list down all the factors of 30, these are—
Method I: 1, 2, 3, 5, 6, 10, 15, 30
Now we will write down all these factors in the form of prime factorization
(2o 3o 5o) (21) (31) (51) (21 31) (21 51) (31 51)
= (21+1+1+1) (31+1+1+1) (51+1+1+1)
=24 34 54 = (30)4.
Method II.
30 = 21 × 31 × 51
14) Answer: a)
Single digit prime numbers are 2, 3, 5 and 7. Out of them smallest is 2.
It gives only O and 1 as remainders. Hence possible numbers must be in the form of K (LCM of 2, 3, 5 and 7) + 1 or 210 k + 1. So, only options (1) are in this format.
15) Answer: d)
