Question

उद्यमिता के विकास में विकासात्मक संस्थाओं के योगदान का वर्णन कीजिए

Answer 1

Answer:

A, B and C can reap the field in = 15 3/4 days = 63/4 days

(A, B and C)’s 1 day work =1/(63/4) = 4/63

B, C and D can reap the field in = 14 days

B, C and D’s 1 day work = 1/14

C, D and A can reap the field in = 18 days

C, D and A’s 1 day work = 1/18

D, A and B can reap the field in = 21 days

D, A and B’s 1 day work = 1/24

Now adding (A+B+C+D),

3[A+B+C+D] = 4/63 + 1/14 + 1/18 + 1/21

= (8+9+7+6)/126

= 30/126

= 5/21

(A+B+C+D) = 5/(21×3) = 5/63

∴ A, B, C and D together can reap the field in = 1/(5/63) = 63/5 = 12 3/5 days.
