Verified Answer
Q.A new subject is added to the curriculum of Grade 8 such that the we...
(B ) 10%
Current percent for Chemistry = 25%
25% of 460 = 115
Reducing marks by 23 will give = 115 – 23 = 92
92 of 460 = (92/460)×100 = 20%
So, percentage of Chemistry has been reduced by 5%.
In the same way, current percentage for Physics = 15%
15% of 460 = 69
Reducing marks by 23 will give = 69 – 23 = 46
46 of 460 = (46/460)×100 = 10%
So, percentage of Physics has also been reduced by 5%.
Hence, the percentage for new subject will be 5%+5% = 10%
