Answer»  the correct answer is 263 SP of washing machine 1 = Rs. 9900 Gain = 10 percent. So let the CP be x, So, 9900 ( SP)= x + 10x/100 = 11x/10; So, x = 99000/11 = 9000 rupees SP of washing machine 2 Rs. 9900 Loss = 10 percent So, let the CP be x, So, 9900 (SP) = x - 10x/100 = 9x/10; SO, x = 99000/9 = 11000 rupees So, Total CP = 9000 + 11000 = 20000 rupees Total SP = 9900 + 9900 = 19800 rupees So, profit = 200 rupees So profit percent = 200/ 20000 * 100 = 1 percent Answer : Gain percent of 1 percent Gain of 10% in whole transaction Loss 1% is in that whole transaction  |
