The smallest part is 12
Explanation:
Given:
76 is divided into four parts in the ratio 7:5:3:4
To find:
The smallest part is
==>Let, the four parts be a,b,c and d
==> a+b+c+d=76
==> The ratio of divided part is 7:5:3:4
==> a = 7x
==> b = 5x
==> c = 3x
==> d = 4x
Apply the values,
==> 7x+5x+3x+4x = 76
==> 12x+3x+4x=76
==> 15x+4x=76
==> 19x = 76
==> x=76/19
==> x=4
==> a = 7(4)
==> a=28
==> b = 5(4)
==> b=20
==> c = 3(4)
==> c = 12
==> d = 4(4)
==> d=16
Comparing a,b,c and d
(A): 12
The smallest part is 12
