After dividing an amount into two parts, Mr. Suresh invests these parts in two different business. In first, he gains 50% profit whereas in second he has a loss of 25%. Total profit of Mr. Suresh in first business is 1888 rupee. What is the total investment of Mr. Suresh if he gains 23% profit over all.
Let total investment = P & part investments are x & (P – x)
According to given condition
x/2 = 1888 implies x = 3776
Similarly according to other condition
3x/2 +(3/4)(P – x) = P 123/100
=>3/2 * 3776 +(3/4)(P – 3776) = P 123/ 100
=>3 * 1888 + (3 /4) P – 3 * 944 = 123 P/100
=>5664 – 2832 = 123 P /100 – (3/4) P
=>2832 = (123 P – 75 P)/100
=>2832 = 48 P/100
=>P = 2832 * 100/ 48 = 5900.
