Net outflow rate when both pipes operate would be x-240 liters/hour.
Capacity of the tank = x*10 hours = (x-240)*(10+6) hours
10x=(x-240)*16 --> x=640 --> capacity = 10x = 6400 liters.

"None of these",
"Rs. 5,100",
"Rs. 4,900",

Let us assume Mr. Karan borrowed amount is Rs. A. (the principal)
By formula of simple interest, S.I. = PRT / 100
Where P = The principal, R = Rate of interest as a %, T = Time in years
S.I. = (P * 6 * 9)/100 = 54 P/100
Amount = Principal + S.I.
8110 = P + (54P/100)
8110 = (100P + 54P)/100

The price of 10 chairs is equal to that of 4 tables. The price of 15 chairs and 2 tables together is Rs. 4000. The total price of 12 chairs and 3 tables is: | [
"Rs. 3900",
"Rs. 3750",
"Rs. 3500",
"Rs. 3840"
] | A | EXPLANATION
Let the cost of a chair and that of a table be Rs. x and Rs. y respectively.
Then, 10x = 4y or y = 5b/2 x
15x + 2y = 4000
15x + 2 x 5/2 x= 4000
20x = 4000
x = 200.
So, y = 172 = 500.
Hence, the cost of 12 chairs and 3 tables = 12x + 3y
= Rs. (2400 + 1500)
= Rs. 3900.

A grocer purchased 80 kg of sugar at 13.50 per kg and mixed it with 120 kg sugar at 16 per kg. At what rate should he sell the mixture to gain 17%? | [
"16 per kg",
"17 per kg",
"16.5 per kg",
"17.55 per kg"
] | D | C.P. of 200 kg of mixture = (80 × 13.50 + 120 × 16)
= 3000.
S.P. = 117% of 3000 = (117⁄100 × 3000) = 3510
∴ Rate of S.P. of the mixture = (3510⁄200) per kg
= 17.55 per kg.

"39",
"39.74",
"39.47",
"39.64"
] | C | Explanation :
After 10 days : 120 women had food for 25 days.
Suppose 95 women had food for x days.
Now, Less women, More days (Indirect Proportion)
95 : 150 :: 25 : x
=> 95 x x = 150 x 25
=> x = 150 x 25 / 95
=> x = 39.47

The cyclist travels 28 miles in 60 mins, so in 5 mins he will travel [(28*5)/60] miles, which equals 7/3 miles in 5 mins.
Now the hiker travels 4 miles in 60 mins. To travel 7/3 miles, he will take [(60*7/3)/4] = 35 mins.
