Hi all
Just to take advices and suggestions
Question is
for Company A 1st month
electronics ---2 million , electrical ---6 million ,
mechanical --- 10 million ,
civil ----90 million
if the proportion remains same for all in second month and electronics has an increase of 5 million
what will be the value for electrical and mechanical in second month
_0.jpg){kind=small}
----------------------------------------|--------------------------------------------------
Electronics 2 Million | 2/108 = 0.0185
Electrical 6 Million | 6/108 = 0.0556
Mechanical 10 Million | 10/108 = 0.0926
Civil 90 Million | 90/108 = 0.833
Total 108 Million |
Electronics has an increase of 5 Mn in 2nd Month which means
Electronics in 2nd month = 7 Mn = 1.85% ( from the table as the proportion in month 2 is same as month 1)Electrical + Mechanical in 2nd Month = 5.56% + 9.26% = 14.82%
if 1.85% is Equivalent to 7 Mn
(14.82/1.85) * 7 Mn
[Edit]56.08 Mn
So Electrical + Mechanical in Month 2 = 56.08 Million
