Choose the correct answer:

$ (698 \times 7)+(72 \times 8)= $
a. 5563
c. 5462
b. 4526
d. None of these

Given:

\( (698 \times 7)+(72 \times 8)= \).

To do:

We have to simplify the given expression.

Solution:

$(698 \times 7)+(72 \times 8)=(700-2)\times7+72\times(10-2)$

$=700\times7-2\times7+72\times10-72\times2$

$=4900-14+720-144$

$=(4900+720)-(14+144)$

$=5620-158$ $=5462 $

Therefore,

$(698 \times 7)+(72 \times 8)=5462$.
