Correct Answer: $40
Explanation:
Correct Answer: $75
Explanation:
Correct Answer: $600, $525, $275
Explanation:
Correct Answer: 8 days
Explanation:
? In 5 days , (4 men + 6 women ) get ? 1600.
? In 1 day, (4 men + 6 women) get ? 1600/5 = ? 320 ....(i)
In 1 day number of person to get ? 1 = 320 / 4 men + 6 women ....(ii)
Similarly, in second condition,
In 1 day, number of person to get ? 1 = (1740 / 6) x (3 men + 7 women)
= 290 / (3 men + 7 women) ....(iii)
From Eqs. (ii) and (iii), we get
320 / (4 men + 6 women) = 290 / (3 men + 7 women)
96 men + 224 women = 116 men + 174 women
? 20 men = 50 women
? Man / Women = 5/2
? 1 women = 2/5 man
From Eq. (i), 1 day,
(4 men + 6 women) = (4 men + 6 x 2/5 men) = 32/5 men get ? 320
? In 1 day, 1 man get = 320 x 5 /32 = ? 50
? In 1 day, 1 woman get = 50 x 2/5 = ? 20
? In 1 day, (7 men + 6 women) get
7 x 50 + 6 x 20 = ? 470
? Required number of days = 3760 / 470 = 8 days
Correct Answer: ? 800
Explanation:
Work for 1 st 2 days = (1/8) + (1/12) = 5/24
? Work for 8 days = (5/24) x (8/2) = 5/6
? Remaining work = 1- (5/6) = (6 - 5) / 6 = 1/6
On 9th day, A's work = 1/8
Remaining work after 9 days = (1/6) - (1/8) = (4 - 3) / 24 = 1/24
B will finish this work in (12 x 1)/24 = 1/2 day
Clearly, A worked for 5 days from starting.
? Work done by A in 5 days = (1/8) x 5 = 5/8
? A's share = (5/8) x 1280 = 5 x 160 = ? 800
