Correct Answer: 105
Correct Answer: 28.75
Correct Answer: 88
Correct Answer: 350
Correct Answer: 100
Correct Answer: 3072
Correct Answer: 3800
Correct Answer: 75
Explanation:
x = 30% of z = 30z/100 = 3z/10
y = 40% of z = 40z/100 = 4z/10
According to the question,(x/y)*100 = p%
p% = 3z/100/4z/100×100= 75%
Correct Answer: 44%
Explanation:
Let initial rent be rs 10
And initial rooms be 10
So initial collection = 10*10 = Rs 100
Now new rent = 10 + 20% of 10 = 12
New no of rooms = 10 + 20% of 10 = 12
So new collection = 12*12 = 144
% change in collection = (144-100)/100*100 = 44%
