1.WHAT IS THE POSSIBLE VALUE OF A?
a)3
b)4
c)7
d)9
2.WHAT IS THE VALUE OF G+A+T+E????
a.16
b.19.
c.24
d.25
3. What is the correlation between S,I,T
a)they are in A.P
b)they are in G.P
c)both (a) and (b)
d)none of these

where can i get these type of problems(site/book ) pls let me knw

take the probable values,that means in the second line a*age is 3 digits.a should take the values of 3 or 2 or 1(3*3=single digit)..in a similar fashion o+o+o is o,the probable values are 0 or 5...do it like that,ull get the ans.

pls some one explain it properly in detail

use back track process since AGE*O=GOTO ie E*O=O, possible only when 1> O=5 and E=3,7,9
2> E=6 and O=2,4,8
now let O=5 now see 2nd column O+(1 OR 2) equals to E so e must be 7. PUT O=5 and E=7.

hav to analyze urslf---
its 317*538

1.A=3

2.19

3.GP

3*o=o.only possible with 5.5*3=15.0=5. o*e=o.hence e must be odd.also 0+1/2=e.hence e can only be 7.e=7.a cannot be >3 else multiplication with a will exceed a 3 digit number.a can be 2,3.try with both you will get a=3,g=1.then remaining can be solved easily.

think 1st about AGE*A= HOG...and so on...

1) a. A= 3
2) b. G=1, A=3, T=8, E=7. Hence G+A+T+E = 19
3) b. S=2, I=4, T =8. Hence SIT is in G.P having r=2
(G.P a, ar, ar^2,..........)
