Question

पुढील विधानातील रिकाम्या जागा भरा.

`a/3 = b/4 = c/7 = (a-2b+3c)/("______") = ("______")/ (6 - 8 +14)`

Sum

Solution

`a/3 = b/4 = c/7 = [a-2b+3c]/bb16 = bb(2a -2b+2c)/{6-8+14}`

स्पष्टीकरण:

`a/3 = b/4 = c/7 = [-2 xx b]/[-2 xx 4] = [3 xx c]/[3 xx 7]`

∴ `a/3 = b/4 = c/7 = [-2b]/-8 = [3c]/21 ={a +(-2b)+3c}/{3+(-8) + 21}`     ...(समान गुणोत्तरांच्या सिद्धांतानुसार)

∴ `a/3 = b/4 = c/7 = (a -2b + 3c)/16`

तसेच,

`a/3 = b/4 = c/7 = (2 xx a)/(2 xx 3) = (-2 xx b)/(-2 xx 4) = [2 xx c]/[2 xx 7]`

∴ `a/3 = b/4 = c/7 = (2a)/6 = (-2b)/-8 = (2c)/14 = [2a+(-2b) + 2c]/[6 + (-8) + 14]`     ...(समान गुणोत्तरांच्या सिद्धांतानुसार)

∴ `a/3 = b/4 = c/7 = [a - 2b + 3c]/16 = (2a - 2b + 2c)/{6 - 8 + 14}`
