Answer:
The no. of buffaloes is 30
Explanaton:
number of ducks+ buffaloes = 70
therefore,
number of buffaloes = 70 - no. of ducks
therefore, b = 70 - d
putting the value of B in equation no. 2
4(70 - d) + 2d = 200
=> 280-4d+2d=200
=>-2d=200-280
=>2d=80
=> d=40
putting the value of d in no. 1
b+40=70
=>b=70-40
=>b=30
therefore the number of buffaloes with the man is 30
