Question

Guddu 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. What is his marks in maths?

Answer 1

Let Guddu marks in geology be G, in physics be P and in maths be M.
Total marks=G+P+M...(1)


P=50....(2)


G=(P+M+G)/4-25

4G=P+M+G-100....(3)


From 2 and 3

3G=50+M-100

3G=M-50
M=3G+50

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