Option 1: 52.2%
Option 2: 49.5%
Option 3: 47.2%
Option 4: 57.0%
Correct Answer: 47.2%
Solution : We know: Equivalent single discount = $(X+Y−\frac{XY}{100})$% where $X$ and $Y$ represent successive discounts. Net discount % for two successive discounts of 12% and 20% = 12 + 20 - $\frac{12\times 20}{100}$ = 29.6% Net discount % for two successive discounts of 29.6% and 25%

Option 1: 0
Option 2: 40
Option 3: 14
Option 4: 26
Correct Answer: 26
Solution : Given: $x^4- 15x^3+ 15x^2- 15x + 40$ = $14^4- 15(14)^3+ 15(14)^2- 15(14) + 40$ = $14^4- (14+1)(14)^3+ (14+1)(14)^2- (14+1)(14) + 40$ = $14^4-14^4-14^3+14^3+14^2-14^2-14+40$ = $26$ Hence, the correct answer is 26.
Question : Simplify: $\frac{(0.73)^3+(0.27)^3}{(0.73)^2+(0.27)^2-0.73\times 0.27}$
Option 1: 1
Option 2: 0.4087
Option 3: 0.73
Option 4: 0.27
Correct Answer: 1
Solution : Since a3 + b3 = (a + b)(a2 + b2 – ab), So, $\frac{(0.73)^3+(0.27)^3}{(0.73)^2+(0.27)^2-0.73\times 0.27}$ = $\frac{(0.73+0.27) [(0.73)^2+(0.27)^2-0.73\times 0.27]}{(0.73)^2+(0.27)^2-0.73\times 0.27}$ = 0.73 + 0.27 = 1 Hence, the correct answer is 1.
