Answer : 1. "4%"
Explanation :

Answer: A) 4% Explanation: SP of first article = Rs.1000   Profit = 20%  CP = SP x 100100+P% = Rs. 25003 SP of Second Article = Rs.1000  Loss = 20%  CP = SP x 100100-L% = Rs. 1250   So, Total SP = Rs.2000; Total CP = Rs.6250/3   As the CP is more than SP, he makes a loss.   Loss = CP - SP = (6250/3) - 2000 = Rs.(250/3)   So, Loss Percent = Lossx100/CP = 4%

Answer : 3. "528"
Explanation :

Answer: C) 528 Explanation: Assume x soldiers join the fort. 1200 soldiers have provision for 1200 (days for which provisions last them)(rate of consumption of each soldier)= (1200)(30)(3) kg. Also provisions available for (1200 + x) soldiers is (1200 + x)(25)(2.5) k As the same provisions are available=> (1200)(30)(3) = (1200 + x)(25)(2.5) x = ([(1200)(30)(3)] / (25)(2.5)) - 1200 => x = 528.
