Question : In $\triangle P Q R, \angle P=90^{\circ}. {S}$ and ${T}$ are the mid points of sides ${PR}$ and ${PQ}$, respectively. What is the value of $\frac{\text{RQ}^2}{(\text{QS}^2 + \text{RT}^2)}$?
Option 1: $\frac{3}{4}$
Option 2: $\frac{4}{5}$
Option 3: $\frac{1}{2}$
Option 4: $\frac{2}{3}$
Correct Answer: $\frac{4}{5}$
Solution : $\angle$ P = 90° Pythagoras theorem Hypotenuse$^2$ = perpendicular$^2$ + base$^2$ Take the sides as shown in the figure S and T are the midpoints of PR and PQ. QR$^2$ = QP$^2$ + PR$^2$ ⇒ QR$^2$ = 2$^2$ + 2$^2$ ⇒ QR$^2$ = 4 +
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. Example 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.) (10, 5, 52) (35, 7, 250)
Option 1: (8, 4, 34)
Option 2: (14, 8, 90)
Option 3: (8, 9, 10)
Option 4: (20, 5, 300)
Correct Answer: (8, 4, 34)
Solution : Given: (10, 5, 52); (35, 7, 250)
Here, (10, 5, 52)→10 ÷ 5 = 2; 10 × 5 = 50; 50 + 2 = 52 (35, 7, 250)→35 ÷ 7 = 5; 35 × 7 = 245; 245 + 5 = 250
Let's
Question : A one-metre pipe is made with an inner diameter equal to the outer radius. How much material (in cubic mitres) is required to make the pipe, if it can hold $\frac{88}{7}$ cubic metres of water in it?
Option 1: 37.7
Option 2: 35.5
Option 3: 33.3
Option 4: 36.6
Correct Answer: 37.7
Solution : Let the radius of the inner cylinder be r and the radius of the outer cylinder be R. Here, 2r = R In this figure, the amount of water that will flow will be equal to the volume of the inner cylinder. The volume of
