A student has to score 40% marks to pass. He gets 172 marks and gets 12 marks more than required to pass. Find the total marks in the examination

Sagot :

Answer: 400

Step-by-step explanation:

Step 1: Express the given conditions mathematically:

The passing marks required = 40% of x = 0.40x

The marks scored by the student = 172

The marks scored by the student = Passing marks required + 12

Step 2: Form equations based on the above conditions:

0.40x = Passing marks required

172 = Passing marks required + 12

Step 3: Solve the equations:

0.40x = Passing marks required

0.40x = 172 - 12

0.40x = 160

Step 4: Find the total marks in the examination:

x =  [tex]\frac{160}{0.40}[/tex]

x = 400

Therefore, the total marks in the examination are 400.

Answer:

If 40%is 172 -12 = 160

therefore 100% = 160/40 ×100

which will give us 400
