Question : What will be the value of $\sin 10^{\circ}- \frac{4 }{ 3} \sin ^3 10^{\circ}?$
Option 1: $\frac{1}{3 \sqrt{3}}$
Option 2: $\frac{1}{6}$
Option 3: $\frac{1}{2 \sqrt{3}}$
Option 4: $\frac{\sqrt{3}}{6}$
Correct Answer: $\frac{1}{6}$
Solution : $\sin 10^{\circ}- \frac{4 }{ 3} \sin ^3 10^{\circ}$ $=\frac{1}{3}(3\sin 10^{\circ}- 4 \sin ^3 10^{\circ})$ $=\frac{\sin3(10^{\circ})}{3}$ [$\because \sin 3 \theta = 3\sin \theta - 4 \sin 3 \theta$] $=\frac{\sin30^{\circ}}{3}$ $=\frac{\frac{1}{2}}{3}$ $=\frac{1}{6}$ Hence, the correct answer is $\frac{1}{6}$.

Question : A retailer offers the following discount schemes for buyers on an item. (i) Two successive discounts of 15% (ii) A discount of 20% followed by a discount of 10% (iii) A discount of 30% Under which scheme the selling price will be the maximum?
Option 1: (ii)
Option 2: (ii) and (iii)
Option 3: (i) and (ii)
Option 4: (i)
Correct Answer: (i)
Solution : We know, Single equivalent discount = $(a+b-\frac{a×b}{100}$)%, where $a$% and $b$% are successive discounts. i) Two successive discounts of 15%: The effective discount, $= 15 + 15 - \frac{15×15}{100} = 27.75$% ii) A discount of 20% followed by a discount of 10%: The effective discount,
Question : Directions: Select the option that is related to the fifth letter cluster in the same way as the second letter cluster is related to the first letter cluster and the fourth letter cluster is related to the third letter cluster. BULL : CDVWMNMN :: SHOT : TUIJPQUV :: TENS : ?
Option 1: UVFGOPTU
Option 2: OPTUUVFG
Option 3: OPTUOPTU
Option 4: UVFGUVFG
Correct Answer: UVFGOPTU
Solution : Given: BULL : CDVWMNMN :: SHOT : TUIJPQUV :: TENS : ?
Add 1 and 2 to the place value of each letter of BULL, to obtain their related letter cluster –
Thus, BULL is related to CDVWMNMN. And, SHOT : TUIJPQUV –
Thus, SHOT

Like, for SCOOTER; S + 7 = Z; C + 6 = I; O + 5 = T; O + 4 = S; T + 3 = W; E + 2 = G;
Question : Simplify the given expression. $(x - 2y)(y - 3x) + (x + y)(x - y) + (x - 3y)(2x + y)$
Option 1: $2y(x - 3y)$
Option 2: $2y(x + 3y)$
Option 3: $2x(x - 3y)$
Option 4: $2x(x + 3y)$
Correct Answer: $2y(x - 3y)$
Solution : Given expression, $(x - 2y)(y - 3x) + (x + y)(x - y) + (x - 3y)(2x + y)$ = $xy-3x^2-2y^2+6xy+x^2-y^2+2x^2+xy-6xy-3y^2$ = $2xy-6y^2$ = $2y(x-3y)$ Hence, the correct answer is $2y(x-3y)$
Question : The value of $\frac{\sqrt[3]{-2744} \times \sqrt[3]{-216}}{\sqrt[3]{\frac{64}{729}}}$ is:
Option 1: 164
Option 2: 152
Option 3: 189
Option 4: 156
Correct Answer: 189
Solution : Given expression, $\frac{\sqrt[3]{-2744} \times \sqrt[3]{-216}}{\sqrt[3]{\frac{64}{729}}}$ = $\frac{\sqrt[3]{-14\times-14\times-14}\times\sqrt[3]{-6\times-6\times-6}}{\sqrt[3]{\frac{4\times4\times4}{9\times9\times9}}}$ = $\frac{-14\times(-6)}{\frac{4}{9}}$ = $\frac{14\times6\times9}{4}$ = 189 Hence, the correct answer is 189.
