Step-by-step explanation:
Explanation:
Less Men, means more Days {Indirect Proportion}
Let the number of days be x then,
27 : 36 :: 18 : x
[Please pay attention, we have written 27 : 36 rather than 36 : 27, in indirect proportion, if you get it then chain rule is clear to you :)]
=>27x = 36 * 18
=> x = 24
So 24 days will be required to get work done by 27 men..
8x+6+4= 3x- 2x- 4 is the correct step
Answer: x > 20
Step-by-step explanation:
x + 10 > 30
-10 -10
x > 20
465+18 = 483
The fraction was just to throw you off, it's not too hard if you look carefully since you get a whole number from it
12:15 does not belong, since that is a ratio of 4:5, whilst the others are all 3:4.
