Two numbers are respectively 20% and 50% more than a third number. The ratio of the two numbers is:
Answer: Option
Explanation:
Let the third number be x.
| Then, first number = 120% of x = | 120x | = | 6x |
| 100 | 5 |
| Second number = 150% of x = | 150x | = | 3x |
| 100 | 2 |
 Ratio of first two numbers = |
 |
6x | : | 3x |  |
= 12x : 15x = 4 : 5. |
| 5 | 2 |

Let c 100.
A = 120.
B = 150.
So the ratio of A to B.
120/150.
4 : 5.
A = 120.
B = 150.
So the ratio of A to B.
120/150.
4 : 5.

20% -----> 4*5=20%
50% ------> 5*10=50%
Ratio is ---- (c) 4 : 5.
So, Option (C) is the Right answer.
50% ------> 5*10=50%
Ratio is ---- (c) 4 : 5.
So, Option (C) is the Right answer.

Suppose the 3rd number is x.
Then first no. will be more than 20% of third no.
So first no.=x+20x/100=6x/5.
second n0.=x+50x/100=3x/2.
so, the ratio of first and second no.=6x/5*2/3x=4:5.
Then first no. will be more than 20% of third no.
So first no.=x+20x/100=6x/5.
second n0.=x+50x/100=3x/2.
so, the ratio of first and second no.=6x/5*2/3x=4:5.

@All.
Here,
First and second numbers 20% and 50% more that means 120:150 simply this we will get 4:5.

Let 3rd number is "c" and the 1st and 2nd is;
A,B.
Then,
A is the 20% more than c.
Means A = c+20%c.
= c+.2c.
= 1.2c.
Same hear,
B is the 50% more than of c.
Means. B = c + 50%c.
= c + .5c,
= 1.5c.
Then the 2 number ratio is,
A:B = 1.2c:1.5c.
(Multiply in both sides 10 to avoid the decimal point)
1.2c * 10:1.5c * 10.
12c:15c,
4:5.
A,B.
Then,
A is the 20% more than c.
Means A = c+20%c.
= c+.2c.
= 1.2c.
Same hear,
B is the 50% more than of c.
Means. B = c + 50%c.
= c + .5c,
= 1.5c.
Then the 2 number ratio is,
A:B = 1.2c:1.5c.
(Multiply in both sides 10 to avoid the decimal point)
1.2c * 10:1.5c * 10.
12c:15c,
4:5.
