3m, 4w, 6b take LCM=12 then devide each with lcm 3m=4 4w=3 6b=2 total work equal to lcm*25 12*25=300 then find efficiency 2M+3w+4b (2*4+3*3+4*2)=25 300/25=12
5Men and 8women can finish ajob in10day while 3men and7women can finish it in 12 days. in how many days 11 men finish it? pls explain sir

  6. 20. 4 men and 6 women can complete a work in 8 days, while 3 men and 7 women can complete it in 10 days. In how many days will 10 women complete it?


  7. 20. 4 men and 6 women can complete a work in 8 days, while 3 men and 7 women can complete it in 10 days. In how many days will 10 women complete it? (4m + 6w) x 8 - (3m + 7w) x 10 (16m 24w) (15m35w)


  8. 20. 4 men and 6 women can complete a work in 8 days, while 3 men and 7 women can complete it in 10 days. In how many days will 10 women complete it? (4m + 6w) 8 = (3m + 7w) 10 (16m 24w) (15m35w) 1m 11 w Total Work = (4 11 +6) 8 = 50 8 = 400 m 11 W 1

  11. 21. A can do a piece of work in 40 days. He works at it for 8 days and then B finished the work in 16 days. How long will they take to complete the work if they do it together Let Efficiency of A >1 Total Work 40 x 1- 40 Work Done in 8 days by A 8 Remaining Work 40-8 32 Efficiency of B-32 -2 16
