1. $10 2.$20

3. $25 4.$50

5. \$75

$$x + 2x + 4x + 8x + 16x = 1550$$

Or, $$x + 2x + 4x + 8x + 16x = 1550$$

Or, $$31x = 1550$$

So, $$x = 50$$, Answer must be (4)

If you look at options u can eliminate 4 options easily.
In the end you need zero hence C & E is not possible
U need 50 as last 2 digit which is again not possible with option A & B.
U left with only option D, plug in the value if you want to verify and you got the answer.

Give Kudos if you think its helpful !!
