Answer 2

Answer:

$M=3G+50$

In maths he got 50 more than 3 times what he got in geography.

Step-by-step explanation:

Given : Guddu's marks in geology is 25 less than 25% of the total marks obtained by him in physics, maths and geology. If his marks in physics is 50.

To find : What is his marks in maths?

Solution :

Let Guddu marks in geology be G, in physics be P and in maths be M.

Total marks=G+P+M  

We have given P=50

and geology is 25 less than 25% of the total marks obtained

i.e, $G=\frac{(P+M+G)}{4}-25$

$4G=(P+M+G)-100$

$3G-P-M+100=0$

Put P=50,

$3G-50-M+100=0$

$3G-M+50=0$

$M=3G+50$

In maths he got 50 more than 3 times what he got in geography.
