Question : In the figure, in $\triangle {PQR}, {PT} \perp {QR}$ at ${T}$ and ${PS}$ is the bisector of $\angle {QPR}$. If $\angle {PQR}=78^{\circ}$, and $\angle {TPS}=24^{\circ}$, then the measure of $\angle {PRQ}$ is:
Option 1: 42$^{\circ}$
Option 2: 39$^{\circ}$
Option 3: 30$^{\circ}$
Option 4: 40$^{\circ}$
Correct Answer: 30$^{\circ}$
Solution : In $\triangle$PQR, PT $ \perp$ QR at T and PS is the bisector of $\angle$QPR $\angle$PQR = 78° and $\angle$TPS = 24° In $\triangle$PQT, $\angle$QPT = 180$^\circ$ – $\angle$PQR – $\angle$PTQ = 180$^\circ$ – 78$^\circ$ – 90$^\circ$ = 12$^\circ$ $\angle$SPQ = $\angle$QPT + $\angle$TPS =

Question : Aditya sold Article X at a profit of 23% and Article Y at a loss of 13%. He earned a profit of INR 180 in the entire transaction. If article X costs INR 90 less than article Y, then what is the price of article Y (in INR)?
Option 1: 2,100
Option 2: 2,007
Option 3: 2,020
Option 4: 2,050
Correct Answer: 2,007
Solution : Let the cost price of Y be $x$. Cost price of X = $x-90$ Profit of X = 23% of $x-90 = 0.23x - 20.7$ Loss of Y = 13% of $x = 0.13x$ Net profit = $0.23x - 20.7 - 0.13x = 0.1x -
Question : When P is subtracted from each of the numbers 8, 6, 2 and 9, the numbers so obtained in this order are in proportion. What is the mean proportional between (3P - 6) and (9P - 4)?
Option 1: 26
Option 2: 28
Option 3: 29
Option 4: 24
Correct Answer: 28
Solution : According to the question, $(8-P)(9-P)=(6-P)(2-P)$ $⇒72+P^2-17P=12+P^2-8P$ $⇒9P=60$ $⇒P=\frac{20}{3}$ Mean proportion between $(3P - 6)$ and $(9P - 4)$ = $\sqrt{(3P - 6)(9P - 4)}$ = $\sqrt{(3×\frac{20}{3} - 6)(9×\frac{20}{3} - 4)}$ = $\sqrt{14×56}$ = $28$ Hence, the correct answer is 28.
Question : $\triangle$ABC is similar to $\triangle$PQR. If the ratio of the perimeter of $\triangle$ABC and the perimeter of $\triangle$PQR is 24 : 16 and PQ = 4.8 cm, then the length (in cm) of AB is:
Option 1: 8.6
Option 2: 7.2
Option 3: 4.6
Option 4: 2.8
Correct Answer: 7.2
Solution :
Given: $\triangle$ABC is similar to $\triangle$PQR. The ratio of the perimeter of $\triangle$ABC and the perimeter of $\triangle$PQR is 24 : 16 and PQ = 4.8 cm. Since, $\triangle$ABC is similar to $\triangle$PQR, We know, The ratio of similar sides of the two similar triangles
Question : Directions: In the following question, select the related number from the given alternatives. 534 : 2 :: ? : ?
Option 1: 102 : 9
Option 2: 553 : 6
Option 3: 884 : 2
Option 4: 999 : 2
Correct Answer: 999 : 2
Solution : Given: 534 : 2 :: ? : ?
Here, 534 : 2→(5 + 3) ÷ 4 = 8 ÷ 4 = 2 Let's check the options – First option: 102 : 9→(1 + 0) ÷ 2 = 1 ÷ 2 = 0.5 ≠
