42x/5 and 44x/5
The required ratio = (42x/5 : 44x/5)= 21 : 22.

Let the two numbers be A and B, here A > B
AB = 266
B = 266/A -----------------(I)
Given,
A – B = 5 ----------- (II)
Substitute from (I) in (II), we get
A – 266/A = 5
A2 – 5A + 266 = 0
(A – 19)(A – 14) = 0
Therefore , A = 19 or A = 14

What is the greatest of 3 consecutive integers whose sum is 30 ? | [
"9",
"5",
"11",
"7"
] | C | The sum of three consecutive integers can be written as n + (n + 1) + (n + 2) = 3n + 3
If the sum is 24, we need to solve the equation 3n + 3 = 30;
=> 3n = 27;
=> n = 9
The greatest of the three numbers is therefore 9 + 2 = 11 Answer: A | AquaRat_train |
