Answer 6

IBM would have to be 10%, because if it was the second lowest (20%), then it's savings would exceed 1/12 of any company.

Answer 7

i didnt understand how 20% would exceed 1/12

Answer 8

20% of 9000 is 1800. 1800*12=21600. The company that saves the most only saves 16800

Answer 9

ok i get it

Answer 11

So whoever invests in operations saves 10800. Now that you have determined that some company saves 10800, you can logically deduce that it must be 18000 saving 60% investing in operations (no other numbers total 10800). Not sure which company it is...

Answer 12

what does iv say? it's cut off?

Answer 13

u can see here

Answer 14

are you sure none of it's cut off?

Answer 15

let me check

Answer 16

sry here it is complete

Answer 17

R&D + company who saves 20% = infosys + 18
can you logically deduce anything from the multiple choice answers? (asking, I don't know myself)

Answer 18

well R&D company can be IBM, Acc or HCL

Answer 19

we also know that R&D cannot be the one that has 18/60%/operations, or the company who saves 20%, or infosys. we also know that they are all different companies.

Answer 20

earlies i also found that

inf, tcs,hcl have turnover;s of 12,18 24 but not in same order

Answer 21

yeah that's the first thing I deduced as well

Answer 22

so it's crucial to note that all 4 of those above are separate companies.

Answer 23

but we also know that the sums = eachother.

Answer 24

so infosys is 24 or 12.

Answer 25

in book it is given that R&D is Acc but i dont know how it deduced

Answer 26

noo don't tell me!

Answer 27

ok

Answer 28

infosys must be 24, and the other 2 are 30 and 12, otherwise the sum would not be possibl

Answer 29

how u deduced that infosys is 24'

Answer 30

it would have to be 24 or 12 because the only things it can be are 12, 18, 24, or 30 for the 4 companies (add to be equal sums). but we know that each company is separate (4 different companies), so logically it'd have to be 18+24=30+12. we know the side with 18 is the company who saves 60%, so infosys must be 24

Answer 31

so 4 companies: tcs, inf, hcl, and acc.
we know acc is the 30, so acc either invests in R+D or saves 20%.
we know inf is the 24. hcl and tcs are the 18 and 12.
tcs does not invest in marketing.
18 invests in operations / saves 60%

Answer 32

oh tcs invests in marketing. oops. that makes it easier.
so tcs invests in marketing, and that means that hcl is the 18 who invests 60%. tcs is the 12.

Answer 33

tcs: 12/?%/marketing
hcl: 18/60%/operations
acc: 30/?%/R&D because it's the last one left

Answer 34

can you update the chart idk how and it simplifies things

Answer 35

yes

Answer 36

\(\large \color{black}{\begin{align}
\begin{array}{|c|c|c|c|} \hline
Company& Area & Turnover\ in\ '000 \ crores & Saving \% \\ \hline
TCS& market & & \\ \hline
HP& sales & 48 & 35\% \\ \hline
IBM& & 9 & 10\% \\ \hline
Acc& & 30 & 25\% \\ \hline
HCL& & & \\ \hline
Inf & & 24& \\ \hline
\end{array}
\end{align}}\)

Answer 37

I also deduced the area of investment for the rest

Answer 38

\(\large \color{black}{\begin{align}
\begin{array}{|c|c|c|c|} \hline
Company& Area & Turnover\ in\ '000 \ crores & Saving \% \\ \hline
TCS& market &12 & \\ \hline
HP& sales & 48 & 35\% \\ \hline
IBM& & 9 & 10\% \\ \hline
Acc& R\&D & 30 & 25\% \\ \hline
HCL& operations & 18 & 60\% \\ \hline
Inf & & 24& \\ \hline
\end{array}
\end{align}}\)

Answer 39

and then finally,
inf and tcs are 20 or 40%
from the equation you have
tcs, inf, hcl, and acc as the 4 companies
acc+ company who saves 20% = infosys + hcl
company who saves 20%: must be tcs
last remaining company who saves 40%: inf!
WE'RE DONE!
that was a ton of fun, when I go to college I'll definitely take logic!

Answer 40

\(\large \color{black}{\begin{align}
\begin{array}{|c|c|c|c|} \hline
Company& Area & Turnover\ in\ '000 \ crores & Saving \% \\ \hline
TCS& market &12 & 20\% \\ \hline

IBM& & 9 & 10\% \\ \hline

HCL& operations & 18 & 60\% \\ \hline
Inf & & 24&40\% \\ \hline
\end{array}
\end{align}}\)

Answer 41

oops! 40% does not invest in HR. so IBM: HR and Inf: Service

Answer 42

\(\large \color{black}{\begin{align}

Answer 43

that was a blast
