Answer 1

hey army firstly to solve these types of questions here is a hint :-

hint : To solve this problem we need to first know that how to find the X% of a quantity Y. X% of the Y would be given as X%ofY=X100×Y. So in this question first we will assume the monthly salary of Rahul equal to a random variable say Rs.X and after that we will calculate the 85% of his salary and then subtract it from the total monthly salary and then will equate it with 3120 to get the value of X. and value of X will be our required answer.

now here is your questions answer

We are given that Rahul spends 85% of his monthly salary and after that his savings per month is Rs.3120, so

To solve this problem, we should know that what is the meaning of percentage,

Y% Percentage is defined as the Y parts per hundred parts of the given quantity.

And Y% of the Z amount is given by = Y100×Z

Now for this question we will first find out the 85% of the monthly salary of the Rahul but before that let us assume the monthly salary of Rahul as Rs.X, so we get

85% of Rs.X as,

=85%ofRs.X=85100×X=85100X

Now total savings of Rahul per month will be given by,

=X−(85%ofRs.X)=X−85100X

Now equating this with the given savings we get,

X−85100X=3120⇒15100X=3120

Cross multiplying we get,

⇒X=3120×10015⇒X=20800

Hence monthly salary of Rahul we get as, Rs.20800
