Answer 1 : Option B
Overall discount = 15+10 - 15*10/100 = 23.5%
Let CP = 100
Sp = 153
so, Mp = 153/(100-23.5) = 153/76.5 * 100 = 200

Now, Discount = 20% ====> SP = 160
CP is 100
Profit% = 60%

ANSWER 2 : Option D
P + K = 1008/(12*7) = 12 pages/day/hr
P is 25% as efficient as K ====> P = 1.25K

So, 2.25 K = 12 -----> K = 16/3
Hence, P + 16/3 = 12 ------> P = 20/3 pages/day/hr
1 page have 333 words. P type words in hour = 20/3 * 333 = 2220

ANSWER 3 : Option D
S1/S2 = (T2/T1)^1/2
So, S1/S2 = 6/5
