16) Each of the following letters represents a number

T+R+A+C+E = 20
C+A+R+E =18
C+A+R+T =16
E+A+R=13

What si the value of R+A+T?

ANS 16



23) The guests at aparty can be seated at tables of 9 with no empty seats.Alternatively,they can be seated at tables of 7 with one empty seat at four or the tables.

Start by looking at what you know.

T R A C E = 20
C A R E= 18.

R+A+C+E = C+A+R+E = 18.
T + R +A+C+E = 20

SO..T MUST = 20-18 = 2.

YOU NOW KNOW THE VALUE OF ONE OF THE LETTERS.

Is it just me...?

No.16:

CARE =TRACE - T (i.e 20 - T) = 18.
Therefore T = 2.

CART = TRACE - E (i.e.20 - E) = 16
Therefore E = 4.

RAT = CART - C
Therefore for RAT also to be 16, C must = 0.

But if EAR = 13 and E = 4, AR = (13 - 4) =9

And we know that T = 2, so RAT = 9 + 2 =11.

Or have missed something?

No, it’s not just you, the answer can’t possibly be 16

ANS 45
The number of people is a multiple of 9.
Lets start with the tables of 7 with 4 empty tables ... lets assume there are only 4 tables. This gives us 24 people, which is not a multiple of 9. Keep adding 7 to the number of people until you arrive at a multiple of 9 and you have the answer.

ANS £280
As we are dealing in percentages, lets assume the original cost of the bike is £100. After a 15% discount, the cost of the bike will be £85. The actual discounted price of the bike is £238. Does that help to calculate the original price?

£238 = 85%
Therefore divide 238 by 8.5
Then multiply by 10
= £280

Well, that's you, me and poor long-suffering DS2, whom I roped in to have a go yesterday evening :).

OP, is the answer given definitely '16', because there doesn't seem to be any logical way that it can be?
