If 19 (36) 13 and 37 (81) 28, then what is the value of 'A' in 43 (A) 38?

Accepted Answer

The pattern is the square of the difference between the outer numbers. (19-13)² = 36, (37-28)² = 81. So, (43-38)² = 5² = 25.

Accepted Answer

Octopus belongs to the phylum Mollusca, characterized by soft bodies. Locusts, butterflies, and scorpions belong to the phylum Arthropoda, known for their jointed appendages.

Question 6

If 3 % 2 = 50, 2 % 4 = 60 then what is the value of 5 % 4 = ?

Accepted Answer

The pattern is (A + B) × 10. For 3 % 2, (3+2)×10 = 50. For 2 % 4, (2+4)×10 = 60. Thus, 5 % 4 = (5+4)×10 = 90.

Question 7

Question 10

In what ratio sugar at Rs 30/kg should be mixed with sugar at Rs 45/kg so that on selling the mixture at Rs 42/kg there is a profit of 20%?

Accepted Answer

Cost price of the mixture = 42 / 1.2 = Rs 35/kg. Using alligation on the cost prices: (45 - 35) : (35 - 30) = 10 : 5 = 2 : 1.

Question 11

What is the sum of the ﬁrst 12 terms of an arithmetic progression if the ﬁrst term is -19 and last term is 36?

Accepted Answer

Use the AP sum formula: S = n/2 × (a + l). Here, n = 12, a = -19, and l = 36. So, S = 12/2 × (-19 + 36) = 6 × 17 = 102.

Question 12

If 6 @ 4 @ 7 = 101 and 2 @ 5 @ 11 = 150, then what is the value of A in A @ 8 @ 9 = 289?

Accepted Answer

The pattern is the sum of the squares of the numbers. A^2 + 8^2 + 9^2 = 289. So, A^2 + 145 = 289, which gives A^2 = 144, meaning A = 12.

Question 13

The 2nd and 8th term of an arithmetic progression are 17 and -1 respectively. What is the 14th term?

Accepted Answer

Let the first term be a and common difference d. a+d=17 and a+7d=-1. Solving gives d=-3 and a=20. The 14th term is a+13d = 20+13(-3) = -19.

Question 14

If CHANTED is coded as ZEXKQBA, then how will MAY be coded as?

Accepted Answer

Each letter in the word is shifted backward by 3 positions in the alphabetical series. Thus, M-3 = J, A-3 = X, and Y-3 = V, giving JXV.

Question 15

In what ratio does the point T(x, 0) divide the segment joining the points S(5, 1) and U(-1, -2)?

Accepted Answer

The y-coordinate of T is 0. Using the section formula for y, 0 = (m(-2) + n(1)) / (m + n). This gives 2m = n, so the ratio m:n is 1:2.

Question 16

In the following question, select the related word pair from the given alternatives. Heart : Organ : : ? : ?

Accepted Answer

The heart is classified as an organ in the human body. Following the same 'Item : Category' relationship, eyes are also classified as organs.
