Question

In a certain code,367 means blue colour car;694 means green colour fan;and 356 means white colour car.what digit in that code means green-a)4,b)either 4 or 9,c)5,d)cannot be determined.​

Answer 1

Answer:-

$\sf{\bold{\red{Option\:(b)}}\:Either\:4\:or\:9}$

$\rule{100}2$

In a certain code 367 means blue colour car, 694 means green colour fan and 356 means white colour car.

→ 367 = blue colour car

→ 694 = green colour fan

→ 356 = white colour car

If we notice carefully then we found that, 6 and colour is common in all.

Means,

$\implies\:\bold{\sf{6 \:codes\: for\: colour.}}$

Also, 3 and car is common in 367 and 356.

→ 367 = blue colour car

→ 356 = white colour car

$\implies\:\bold{\sf{3\:codes\:for\:car.}}$

We have to find that in 694 which digit codes for the green.

From above

→ 6 codes for colour

→ 3 codes for car

What left is.. 9 and 4.

Therefore,

Either 4 or 9 codes for green.

In 356;

→ 3 codes for car

→ 6 codes for colour.

So, 5 codes for white.

Answer 2

$\begin{lgathered} \red{\bf{Given}}\begin{cases} \sf367 = blue \: colour \: car \\ \sf \: 694 = green \: colour \: fan \\ \sf \: 356 = white \: colour \: car \\ \bf \: \green{green} = ? \end{cases}\end{lgathered}$

$\blue{\textbf{Smart approach to solving}} \\ \blue{\bf \: Coding\:-Decoding \:questions : - - }$

→Observe alphabets or numbers given in the question

Try to find the pattern or sequence it follows. They could be in ascending or descending order, arranged in an alternate fashion and other ways as well.

→ Figure out the rule followed by the given arrangement of alphabets/numbers/words...

→ To solve such questions, any two phrases with a common word are picked up. The common code word will refer to that word. Proceeding in a similar manner, all possible combinations of two phrases are selected and a common code is picked up.

$1) \sf\: first \: we \: will \: see \: which \: digit \\ \sf \: and \: word \: is \: common \: in \\ \sf \: all \: three \: given \: codes..$

as we can see Easily Colour is in all three codes and also Digit 6 is all three ...

Hence ,,,

$\red{\boxed{\bf \: colour \: = 6}}$

_____________________________________

$2) \sf \: now \: will \: see \: 2 \: common : - -$

As we can see 367 have Car and also 356 have car common , and digits common in both is 3.. ( As we already got code for 6) ..

Hence,,,

$\red{\boxed{ \bf \: car \: = 3}}$

_____________________________________

$3) \sf\: now \: we \: will \: see \: single \: common$

As we can see from 367 , we get, code for Colour , Car .

From 694, we get, code for Colour.

From 356 , we get, code for Colour , Car .

__________________________________

Now, in 694 , only one digit and word is common,

Hence,,

$\boxed{\bf \: 9 \: or \: 4 = either \: green \: or \: fan}$

$\textbf{As \red{Fan} is not in Any three of them} ....$

We cant Find Exact Code for Fan ..

___________________________________

without This we can Find Exact value of Green also....

Hence, we can say that ,

$\boxed{ \bf {\green{green} = b) \: either \: 4 \: or \: 9}}$
