Question : 5 of 100

Marks: +1, -0

According to a certain code, ‘=' means ‘>', ‘– ' means ‘+', ‘+' means ‘– '. If a, b and c are positive integers and a = b = c, then which of the following are true ?

$\b = \a + \c$
$\ac = \b^{2}$
$\a – \c = 2\b$
$\ab=\c^{2}$

Validate

Solution:

From option (a)
=

\b > \a – \c

also a = b = c
∴

\b > \b – \c

\b > 0

Here a, b & c are positive integer, so option (1) is true.
