Question : What is the difference between a discount of 35% and two successive discounts of 30% and 5% on a bill of INR 10,00,000?
Option 1: INR 15,500
Option 2: INR 15,000
Option 3: INR 14,000
Option 4: INR 16,500
Correct Answer: INR 15,000
Solution : First discount = 35% Successive discounts = 30% and 5% Effective discount = 30 + 5 – $\frac{30 ×5}{100}$ = 35 – 1.5 = 33.5% Required difference = (35 – 33.5)% of 10,00,000 = $\frac{1.5}{100}×10,00,000$ = 15,000 Hence, the correct answer is INR 15,000.
Question : Directions: Select the set in which the numbers are related in the same way as the numbers of the given 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.) (23, 25, 16) (21, 17, 256)
Option 1: (14, 19, 125)
Option 2: (27, 23, 64)
Option 3: (18, 15, 81)
Option 4: (11, 9, 12)
Correct Answer: (18, 15, 81)
Solution : Given: (23, 25, 16); (21, 17, 256)
Here, (23, 25, 16)→(25 – 23)4 = (2)4 = 16 (21, 17, 256)→(21 – 17)4 = (4)4 = 256
Let's check the options – First option: (14, 19, 125)→(19 – 14)4
Question : $\Delta ABC$ and $\Delta DEF$ are two similar triangles and the perimeters of $\Delta ABC$ and $\Delta DEF$ are 90 cm and 54 cm respectively. If the length of DE = 36 cm, then the length of AB is:
Option 1: 60 cm
Option 2: 40 cm
Option 3: 45 cm
Option 4: 50 cm
Correct Answer: 60 cm
Solution : The ratio of the perimeters of two similar triangles is equal to the ratio of their corresponding sides. $\frac{{AB}}{DE} = \frac{\text{Perimeter of $\Delta ABC$}}{\text{Perimeter of $\Delta DEF$}}$ ⇒ $\frac{AB}{36\;cm} = \frac{90\;cm}{54\;cm}$ ⇒ AB = 60 cm Hence, the correct answer is 60 cm.
Question : Directions: Select the option in which the numbers share the same relationship in the set as that shared by the numbers in the given set.
