8. A sum of Rs. 4,27,000 is to be divided
among three friends Parbhat, Kuldip and
Sandeep such that 3 times Parbhat's
share, 4 tunes Kuldip's share and 7 times
Sandeep's share are all equal. The share
of Sandeep is Rs.:
(a) 84,000
(b) 1,40,000
(c) 1,96,000
(d) 2,40,000​

Answer 1

Answer:

z = 84000

Step-by-step explanation:

3x + 4y + 7z = 427000

Since, 3x = 4y = 7z = A

Hence,

A + A + A = 427000

3A = 427000

A = 142333

Now,

7z = A = 142333

z = 20333

The bigger value than 20333 is 84000, hence, the answer is 84000

Answer 2

Answer:

(a) 84000

Step-by-step explanation:

let the proportions be divided as 3x:4y:7z

since 3x=4y=7z= A

then x=A/3 , y=A/4, z=A/7

now,

A/3+A/4+A/7 = 427000

(28A+21A+12A)/84= 427000

61A=427000*84

A = (427000 * 84)/61

A = 588000

to find the value of z=A/7

z= 84000

Hence, The share of Sandeep is Rs. 84000
