% of high quality sunglasses = 70%
% of low quality sunglasses = 25%
% of sunglasses defective = 100% - 95% = 5%

Let X = Rate of 1 cup of tea.
And Y = Rate of 1cup of coffee.
And Z = Max no of cups of coffee he can purchase with the remaining money.
From question we have,
X = 600/24 = 25.
and Y = 1500/15 = 100.
So acc. to the question,
=> 8X + ZY = 2200
=> 8(25) + 100Z = 2200
=> 200 + 100z = 2200

The price of commodity X increases by 45 cents every year, while the price of commodity Y increases by 20 cents every year. In 2001, the price of commodity X was $4.20 and the price of commodity Y was $6.30. In which year will the price of commodity X be 65 cents more than the price of commodity Y? | [
"2010",
"2013",
"2014",
"2012"
] | D | The price of commodity X increases 25 cents each year relative to commodity Y.
The price difference is $2.10 and commodity X needs to be 65 cents more than commodity Y.
$2.75 / 25 cents = 11 years
The answer is 2001 + 11 years = 2012.

The below sequence is a bit tricky. Can you solve it to find the next number?
5, 25, 325, 4325, ? | [
"62819",

Explanation:
Consider 1 = 5
2 = 25
3 = 325
4 = 4325
Then 5 = 54325
See the pattern. With every digit, the previous numbers are added after that digit
So the next number in the series is 54325 | AquaRat_train |

A fruit wholesale dealer has been paid $329,864 in his savings account. What is the least amount of money (in whole number of dollars) that he must add to his account if if he wants to be sure that all 9 of his salesmen have paid evenly? | [
"$4",
"$2",
"$6",
"$3"
] | A | To find the least amount the fruit wholesale dealer should add to his account to ensure all 9 of his salemen have paid evenly,
he needs to make the total divisible by 9
Simply add the individual digits of the total = 3+2+9+8+6+4 = 32
If you add 4 , the number is divisible by 9 (32+ 4)
Correct Option : D | AquaRat_train |
A and B invest in a business in the ratio 3: 2. Assume that 5% of the total profit goes to charity. If A's share is Rs. 855, what is the total profit? | [
"None of these",
"1600",
"1500",
"1400"
] | C | Explanation :
Assume that the total profit is x.
Since 5% goes for charity, 95% of x will be divided between A and B in the ratio 3: 2
=> A's profit = (95x/100) * (3/5) = 855
=> 95x/100 = 855*5/3 = 285*5 = 1425
=> x = 1425 * 100/95 = 285 * 100/19 = 1500
Hence the total profit = 1500. Answer : Option B | AquaRat_train |
