Quants Quiz-

1. A hundred rupee note measures 15 cm × 8 cm and a bundle of 90 such notes is 1 cm thick. Find the value of the hundred rupee notes that can be contained in a box of size 48 cm × 36 cm × 30 cm, if the bundles are tightly packed in it without any empty space.

Volume of the box = (48 × 36 × 30) cubic cm
Volume of each bundle = (15 × 8 × 1) cubic cm
Number of bundles in the box= 48x36x30/15x8x1= 432
Value of each bundle = 9000 ∴ Total value = (9000) (432) = 3888000

2. Tapu bought a few goods for Rs 1800. He sold 33% of the goods bought at 20% loss. Find the profit percentage at which the remainder of the goods must be sold to achieve a benefit of 20%.

Suppose that Tapu purchased 3 kg for Rs 1800 Cost price of 1 kg = Rs. 600.
He sold one kg at a loss of 20%. Hence his selling price of this kg = Rs. 480.
His total selling price must be (1.2) × 1800 = Rs. 2160
Hence selling price of the remaining 2 kg must be Rs 1680. Cost price of 2kg = 2 × 600 = Rs. 1200
∴Profit percentage = 1680 – 1200/1200 x 100 = 40%

3. A vessel has 400 litres of pure milk. 40 litres of milk is removed from the vessel and replaced by water. 40 litres of the mixture thus formed is replaced by water. This procedure is repeated once again. Find the percentage of milk in the resultant solution.

Let v litre be volume of milk with a concentration of c1%. If x litres of the solution is removed and replaced with water, the new concentration ((v-x)/v) x c1. Given that initial concentration is 100%. (pure milk), v = 400, x = 40 and the replacement is done thrice.
∴ Concentration of milk in the resultant solution = (400-40/400)3 x 100 = 72.9%

4. A year ago the proportion of Walter’s and Jesse’s compensations was 3 : 5. The proportions of their individual pay rates of a year ago and present year are 2 : 3 and 4 : 5 respectively. If their combines pay for the current year is Rs.86,000, find the current pay of Walter.

Given the ratio of Walter’s salaries, last year and present year is 2 : 3
So, let the salary of Walter last year be Rs. “2x” and present year be Rs. “3x”

The ratio of Jesse’s salaries, last year and present is 4 : 5
So, let the salary of Jesse last year be Rs. “4y” and present year be Rs. “5y”

Given that, ratio of Walter’s and Jesse’s salary 1 year ago = 3 : 5

Then, we can write
2x / 4y = 3 / 5
⇒ 10x = 12y
⇒ 5 x = 6 y
⇒ y = 5x/6 …… (i)

Also, given in the question,

Their combined salary for the present year is Rs. 86000
∴ 3x + 5y = 86000

Substituting the value of y from (i)
⇒ 3x + 5*(5x/6) = 86000
⇒ 18x + 25x = 516000
⇒ 43 x = 516000
⇒ x = 12000

And, y = 5 * 12000 / 6 = 10000

Thus, Walter’s present salary is
= 3x
= 3 * 12000
= Rs. 36000

5. Mumbai Indians and Chennai Super Kings play 20 overs cricket series until one team wins 4 matches. No match ends in a draw. Find in how many ways the series can be won?

Taking M for Mumbai Indians and C for Chennai Super Kings. We can arrange M and C to show the wins for Mumbai Indians and Chennai Super Kings respectively.
e.g. : CMMMM means first match is won by Chennai Super Kings which is followed by 4 wins by Mumbai Indians. This is one way in which series can be won.
Suppose Mumbai Indians wins the series, then last match is always won by Mumbai Indians.

∴ Total number of ways =35
In the same number of ways India can win the series.
∴ Total no. of ways in which the series can be won 35×2=70

LRDI Quiz-

1. Priyanka, Jelda, Neha, Yamini, and Lata take part in a race. There are atleast two girls ahead of each Neha and Priyanka. No more than one girl is behind Lata and Priyanka each.
