Answer d)Cannot be determined
Let, A’s salary be Rs 8x and B’s salary be Rs 7x.
After respective increases, we have,
A’s salary = Rs(120*8x/100)
B’s salary = Rs (110*7x/100)
so A:B= 96:77
Hence We get no result.

M’s share = Rs ( 3/8*44352)= Rs= 16632
Remaining amount = Rs (44352 – 16632) = Rs 27720
N’s share= Rs( 1/6*27720)= Rs. 4620
so P’s share = Rs(2/5*4620)= Rs 1848.
