Question 164

7474 + 4747 = ? $$\times$$ 25

Solution

Option C:

As each of the options given have 2 decimal places, we need to find a precise answer.

Now, 7474 + 4747 can be broken down into two parts due to symmetry and then summed up.

i.e. 7400 + 4700 + 74 + 47

= 12100 + 121

Now, $$ ? = (12100 \div 25) + (121 \div 25) $$ which gives $$484 + 4.84 = 488.84.$$
