EQUATION ANALYSIS TEST

by Will Shortz

This test does not measure your intelligence, your fluency with words, and certainly
not your mathematical ability. It will, however, give you some gauge of your mental flexibility
and creativity. In the three years since we developed the test, we've found few people
who could solve more than half the 24 questions on the first try. Many, however, reported
getting answers long after the test had been set aside -- particularly at unexpected
moments when their minds were relaxed, and some reported solving all the questions
over a period of several days. Take this as your personal challenge.

Instructions: Each equation below contains the initials of words that will make it correct. Find the missing words.

For example, 26 = L. of the A. would be 26 = Letters of the Alphabet.

26 = L. of the A.
7 = W. of the A.W.
1,001 = A.N.
12 = S. of the Z.
54 = C. in a D. (with the J.)
9 = P. in the S.S.
88 = P.K.
13 = S. on the A.F.
32 = D.F. at which W.F. br> 18 = H. on a G.C.
90 = D. in a R.A.
200 = D. for P.G. in M.
8 = S. on a S.S.
3 = B.M. (S.H.T.R.!)
4 = Q. in a G.
24 = H. in a D.
1 = W. on a U.
5 = D. in a Z.C.
57 = H.V.
11 = P. on a F.T.
1,000 = W. that a P. is W.
29 = D. in F. in a L.Y.
64 = S. on a CB.
40 = D. and N. of the G.F.

In its annual 1981 issue of "What's hot and what's not," Us Magazine named the Equation Analysis Test in the
"What's hot" category -- the only nonperson so recognized.

Shortz reports:

Some anonymous person had retyped the puzzle from Games (word for word, except for my byline), photocopied it, and passed it along. This page was then rephotocopied ad infinitum, like a chain letter, and circulated around the country. Games readers who hadn't seen the original even started sending it back to Games as something the magazine ought to consider publishing!
