Question

Ranjan scored 45% marks in the First paper and 70% in the second paper. How much percentage should gets in the third paper so as to get 60% as overall score?
​

Answer 1

Answer:

65 %

Step-by-step explanation:

Concept of Averages

subject 1= 45%

sub 2 = 70%

if he needs 60% as overall score

his total score must be 180

then only 180/3 = 60% (3 = the no of subjects)

so he has 45 + 70 =115

he needs to score 180 -115 = 65 marks

to get 60% in the overall score

Ranjan scored 45% marks in the First paper and 70% in the second paper. How much percentage should gets in the third paper so as to get 60% as overall score?

$\huge{\underline{\green{✬solution:-}}}$

Rajan score marks in first paper =45%

he scores in second paper =70%

let he scores in third paper =x%

• over all score means over all average

his average=60%

• formula of average=

$\sf\underline{\underline{\purple{ \frac{total \: percentage}{no \: of \: percentage} }}}$

using formula our equation=

60=(45+70+x)/3

=>3(60)=115+x

=>180-115=x

=>x =65
