Question
P started a business with an investment of Rs.10000,
after 6 months Q joined him with Rs.14000 and after another 6 months R joined them with Rs.18000. If after end of two years profit share of Q is Rs.8400, then what is the total profit earned by them?Solution
Ratio of profit share of P, Q and R = 10000 x 24 : 14000 x 18 : 18000 x 12 = 20 : 21: 18 Required amount = 8400 x (59x/21) = Rs.23600
I. 3x2 = 2x2 + 9x – 20
II. 3y2 = 75
I. x2 – 9x + 18 = 0
II. y2 – 5y + 6 = 0
I. 2x² - 9x + 10 = 0
II. 3y² + 11y + 6 = 0
I. x² - 33x + 270 = 0
II. y² - 41y + 414 = 0
I. 27x6 - 152x3 + 125 = 0
II. 216y6 - 91y3 + 8 = 0
