.......QUANTITATIVE REASONING........
A housewife forgot her Bank account PIN CODE which is a 5 - digit number, but luckily she remembered some hint on how to recall this PIN CODE
(1)The first digit is the square of
the second
(2)The sum of the second and
third is 10
(3)The fourth is equal to the
second plus 1
(4)The third and fifth makes 14
(5)The sum of all the digits is 30
What's the PIN CODE

What's the PIN CODE
let the digit be a, b, c, d, and e.
(1) a = b^2
(2) b + c = 10
(3) d = b + 1
(4) c + e = 14
(5) a + b + c + d + e = 30
from 5
a+b+d+c+e = 30
subs 4
a+b+d +14 = 30
a+b+d = 16
sub 3
a+b+b+1=16
a+2b=15
sub1
b^2 + 2b - 15 = 0
(b + 5)(b - 3) = 0
b=3, since a pincode cant be negative.
a = 9
b = 3
c = 7
d = 4
e = 7
