Answer & Explanation

7. 3; 360 * 9/10 * 3/4 = 243

8. 4;
(480 + 350 + 380 + 500 + 540) × 40 % = 900

9. 3;

10. 1;
(320 + 350 + 300 + 360 + 340)/(400 + 380 + 410 + 430 + 390) * 100
= 1670/2010 * 100 = 83.08%

11. 2;
(420 + 380 + 410 + 520 + 460) ×10 %
= 2110 * 10/100 = 211

12. 3;
(400 + 380 + 410 + 430 + 390)/ 5 = 2010/5 = 402
