Question

Ajay got 80% marks in physics and 75% in chemistry in the CBSE board exams. The maximum marks in Physics and Chemistry was 70. He scored 90% in Maths where the maximum marks were 100. Find out his net percentage in PCM.

Answer 1

Answer:

82.7%

Step-by-step explanation:

marks in physics = 80% × 70 = 80×70/100 = 56

marks in chemistry = 75% × 70 = 75×70/100 = 52.5

marks in maths = 90% × 100 = 90×100/100 = 90

net percentage in PCM = (56+52.5+90)×100/(70+70+100) = 198.5×100/240 = 82.7%
