Question 5

Among three numbers, the first is twice the second and thrice the third. If the average of three numbers is 429, then what is the difference between the first and  the third number?

Accepted Answer

Let the numbers be x, y, z. x = 2y and x = 3z. So, y = x/2 and z = x/3. Average (x + x/2 + x/3)/3 = 429. Solving for x gives x = 702. The third number z = x/3 = 234. Difference = 702 - 234 = 468.

Question 6

A rice trader buys 16 quintals of rice for Rs 1,280. 18% rice  is lost in transportation. At what rate should he sell to earn 23% profit?

Accepted Answer

Calculate the cost price per quintal. Account for 18% loss in quantity. Then, determine the selling price per quintal to achieve a 23% profit on the original cost.

Question 7

If (1/4 of x) - (4/5 of 6/7) equals - 9/7, then value of x is

Accepted Answer

Set up the equation: (1/4)x - (24/35) = -9/7. Convert -9/7 to -45/35. Add 24/35 to both sides: (1/4)x = -21/35 = -3/5. Multiply by 4: x = -12/5 = -2.4.

Question 8

Accepted Answer

First, solve the linear equation 8x - 4 = 3x + 6 to find x. This gives 5x = 10, so x = 2. Then substitute x = 2 into (x+1)³ to get (2+1)³ = 3³ = 27.

Question 13

To cover a distance of 333 km in 2 hours by a car, what should be the average speed of the car (in meter/second)?

Accepted Answer

First, calculate speed in km/hr: 333 km / 2 hr = 166.5 km/hr. Then convert to m/s by multiplying by 5/18: 166.5 * (5/18) = 46.25 m/s.

Question 14

Select the antonym of deep-seated

Accepted Answer

Deep-seated means firmly established or ingrained. The opposite is something that is not permanent or lasting, which is 'temporary'.

Question 15

If the amount received at the end of 2nd and 3rd year at compound interest on a certain Principal is Rs 30250, and Rs 33275 respectively, what is the rate of interest?

Accepted Answer

The difference between the amounts at the end of the 3rd and 2nd year is the interest for the 3rd year on the 2nd year's amount. Calculate this difference and divide by the 2nd year's amount to find the rate.

Question 16

10% discount is offered on an item. By applying a promo code the customer wins 20% cash back. What is the effective discount?

Accepted Answer

Assume item price is 100. After 10% discount, price is 90. 20% cashback on 90 is 18. Total discount is 10 + 18 = 28. Effective discount is 28%.

When a discount of 20% is given on an African safari ticket, the profit is 43%. If the discount is 28%, then the profit is

Accepted Answer

Assume CP=100. With 43% profit, SP=143. Since 20% discount is given, MP = SP / (1-0.20) = 143 / 0.8 = 178.75. If discount is 28%, new SP = 178.75 * (1-0.28) = 178.75 * 0.72 = 128.7. New profit = 128.7 - 100 = 28.7%.

Question 19

If 5x + 2 > 3x + 1 and 4(x - 4) - 2 ≤ 3x - 1, then x can take which of the following values?

Accepted Answer

Solve the first inequality: 5x + 2 > 3x + 1 gives 2x > -1, so x > -0.5. Solve the second: 4x - 16 - 2 ≤ 3x - 1 gives x ≤ 17. Combining these, -0.5 < x ≤ 17. Only 16 satisfies this range.

Question 20

Δ ABC and Δ DEF are similar triangles. Length of AB is 10 cm and length of the corresponding side DE is 6 cm. What is the ratio of Perimeter of ΔABC to ΔDEF?

Accepted Answer

For similar triangles, the ratio of their perimeters is equal to the ratio of their corresponding sides. So, Perimeter(ABC) : Perimeter(DEF) = AB : DE = 10 : 6 = 5 : 3.
