Question

2) If y exceeds x by 20%, then x is less than y by?
(a) 16%
(b) 16 1/3 %
(c) 16 2/3%
(d) 16 3/5%
​

Answer 1

Answer:

$16\frac{2}{3}$ %

Step-by-step explanation:

Let us assume that the value of x = A

Given that the value of y exceeds the value of x by 20%.

So, the value of y will be =$A+A\frac{20}{100}$

                                         =$A+0.2A$

                                         =$1.2A$

Now, we have to find by how much percentage does x less than y.

So, x is less than y by the amount (1.2A-A)=0.2A.

Therefore, the required percentage is equal to

$\frac{0.2A}{1.2A}*100$ %

=$\frac{100}{6}$ %

=$16\frac{2}{3}$ %

Answer 2

Answer:

short-cut method :-

Let x=100 so, y=120

Let x=100 so, y=120now,

Let x=100 so, y=120now, since, 120 is -----} 20% less

Let x=100 so, y=120now, since, 120 is -----} 20% less so 100 is -----} 20/120 ×100 % less

Let x=100 so, y=120now, since, 120 is -----} 20% less so 100 is -----} 20/120 ×100 % less -----} 2000/120 % less

Let x=100 so, y=120now, since, 120 is -----} 20% less so 100 is -----} 20/120 ×100 % less -----} 2000/120 % less -----} 16 2/3% less

Let x=100 so, y=120now, since, 120 is -----} 20% less so 100 is -----} 20/120 ×100 % less -----} 2000/120 % less -----} 16 2/3% less mark it as brainliest
