ans 6*4 =24
4. complete the series
1, 2, 3, 5, 16,_
ans 231
approach
2^2-1^2=3
3^2-2^2=5
5^2-3^2=16
16^2-5^2=231
1, 2, 3, 8, -, 224
ans 27
approach
2*1+1=3
2*3+2=8
3*8+3=27
27*8+8=224
5. one watch gains 1minute/hr another watch loses 2minute/hr. in how much time the difference of time between them would be
one hour.

what is the temperature where they both are equal?
ans 52.5 degrees
approach
let the temp be =X
and caliberation in A=a
caliberation in B=b
A(X-14)=B(X-36)
A(X-133)=B(X-87)
thus
(x-14)(x-87)=(x-36)(x-133)
solving
x=52.2
9. a man picking up letters in a way that when picks up one misses one, picks up another one misses 2, picks up another
