Question : What will be the cost price of the goods if a shopkeeper allows a discount of 10% on the marked price of Rs. 100 and gains 8% (rounded off to the nearest integer)?
Option 1: Rs. 83
Option 2: Rs. 86
Option 3: Rs. 87
Option 4: Rs. 81
Correct Answer: Rs. 83
Solution : Marked price = Rs. 100 Discount = 10% of marked price = Rs. 10 ⇒ Selling price = 100 – 10 = Rs. 90 Also, profit = 8% of cost price So, the selling price – cost price = 8% of the cost price
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the following sets.(NOTE: Operations should be performed on the whole numbers, without breaking down the numbers into their constituent digits. E.g. 13 – operations on 13 such as adding/subtracting/multiplying etc. to 13 can be performed. Breaking down 13 into 1 and 3 and then performing mathematical operations on 1 and 3 is not allowed.) (13, 28, 58) (16, 34, 70)
Option 1: (15, 32, 64)
Option 2: (18, 36,110)
Option 3: (11, 24, 50)

Correct Answer: silica, alumina
Solution : The correct answer is silica, alumina.
Alumina and silica comprise the bulk of the continental mass's mineral composition. As a result, it is referred to as sial (si-silica and al-alumina). The continental crust is made up of sial. Silica and alumina are referred to
Question : Direction: A word is represented by only one set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as in two matrices, given below. The columns and rows of Matrix (I) are numbered from 0 to 4 and that of Matrix (II) are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, e.g. 'L' can be represented by 12,24, etc and 'R' can be represented by 55, 67, etc. Similarly, you have to identify the set for the word 'SENT'
Option 1: 10, 20, 58, 77
Option 2: 22, 32, 65, 78
Option 3: 34, 44, 67, 87
Option 4: 41, 13, 87, 68
Correct Answer: 22, 32, 65, 78
Solution : Here, from the matrices (Matrix 1 and matrix 2) we get the numbers that represents the letters of the word 'SENT' —
S — 03, 10, 22, 34, 41
E — 01, 13, 20, 32, 44
N — 58,

Question : If $\sec A - \tan A = p$, then find the value of $\sec A$.
Option 1: $\frac{p^2-1}{p^2+1}$
Option 2: $\frac{\mathrm{p}^2+1}{\mathrm{p}^2-1}$
Option 3: $\frac{\mathrm{p}^2+1}{\mathrm{p}}$
Option 4: $\frac{\mathrm{p}^2+1}{2 \mathrm{p}}$
Correct Answer: $\frac{\mathrm{p}^2+1}{2 \mathrm{p}}$
Solution : $\sec A - \tan A = p$ $\frac{1}{\cos A} - \frac{\sin A}{\cos A} = p$ $\frac{(1-\sin A)^2}{(\cos A)^2} = p^2$ $\frac{(1-\sin A)^2}{1-\sin^2 A} = p^2$ $\frac{(1-\sin A)^2}{(1-\sin A)(1+\sin A)} = p^2$ $\frac{1-\sin A}{1+\sin A}= p^2$ $1-\sin A = p^2 + p^2\sin A$ $\sin A
