Of three numbers, the third is four times the second and the second is two times the first. If their average is 165, the smallest of the three numbers is: | [
"19",
"22",
"21",
"45"
] | D | Explanation:
Let first number be x.
So,2nd no. = 2x & 3rd no.=8x.
So,x+2x+8x=165 × 3 = 495
11x = 495/11
x = 495/11
Hence,smallest Number x=45

If 200 lb of a mixture contain 80% husk and 20% sand. Then how much husk needs to be extracted in order to have 75% concentration of Husk? | [
"60",
"20/3",
"40",
"1/2"
] | C | We need to extract 40 lb of husk.
80 % of 200 = 160
20 % of 200 = 40
Now we have t remove husk to have 75 % of Husk ( key point sand is not supposed to be removed)
Let X be the new quantity after removing husk
So, 40 = 25 % of X
X = 160
Husk will 120 lbs , hence we need to remove 1/4 of the total husk or 40 lbs

"Rs. 7500",

(x * 14 * 2)/100 + [(13900 - x) * 11 * 2]/100 = 3508
28x - 22x = 350800 - (13900 * 22)
6x = 45000 => x = 7500
So, sum invested in scheme B = (13900 - 7500) = Rs. 6400.
