Arjun is twice as old as Shreya. If five years ago his age was three times Shreya's age, then Arjun's present age is
drek231 [11]

Answer:

Arjun is 20 years old and Shreya is 10 years old.

Step-by-step explanation:

5 YEARS AGO-

Arjun: 2x-5

Shreya: x-5

NOW-

Arjun: 2x

Shreya: x

EQUATION-

2x-5=3(x-5) = 2x-5=3x-15

(add 15 on both sides)

2x+10=3x

(subract 2x from both sides)

x=10

Therefore, Arjun is 20 years old and Shreya is 10 years old :)

6% of what number is 270? 4,500 450 45 4.5
Gnoma [55]

So to solve this problem, we can either do guess and check, or solve an equation.


Let's do the equation, since it will work for all problems, even when you're not given a list of possible answers.


So, to begin, let's define our unknown.

We can represent the number as "n"


So, 6 percent of "n" is equal to 270

To find a "percent" of a number, you need to multiply the number by the percentage.

So, 6 percent as a decimal is .06

This is because a percent is a fraction divided by 100 (6/100)


.6\times n=270\\\n=270\div.6\\n= 4500


The number is 4,500
