# Plugging In: Invisible Plugging In - Percents

Jane appeared for a four-part exam that allocated 60%, 25%, 10%, and 5% weight to sections I, II, III, and IV, respectively. If she scored 75% on part I, 80% on part II, 70% on part III, and 80% on part IV, what is her overall score in percents for the combined exam?
Did you use the 10% block to estimate these percents?

The 10% block is the fastest way to __Ballpark__ percents in the GMAT. For 10%, just move the decimal point one spot to the left. If you need 60%, multiply by 6. If you need 5%, figure out what 10% is and then take half of that.
Correct. [[snippet]] __Plug In__ 100 for the top score of each part. Hence, Jane scored 75, 80, 70, and 80 on parts I, II, III, and IV, respectively. Then Jane's weighted scores areas are as follows: - Part I: 60% of 75 is 45 - Part II: 25% of 80 is 20 - Part III: 10% of 70 is 7 - Part IV: 5% of 80 is 4 Therefore, Jane's overall score is \$\$45+20+7+4=76\$\$.
