These are questions that are always on public service exams. ✔One of the biggest challenges for students and exam takers when taking the exam is knowing how to interpret the math problem. 🔴 Video Questions 🔴 ✅ 1) (FCC) Father and son share the same birthday. Today, the father's age is 3 years less than four times his son's age. In exactly 20 years, the father's age will be 1 year more than twice his son's age. When the son was 5 years old, the father's age, in years, was (A) 37. (B) 40. (C) 43. (D) 38. (E) 35. ✅ 2) (Administrative Assistant - FCC - 2016) The age difference between father and son is 25 years. Today, with the son being 10 years old, the father's age is 35, therefore 3.5 times his son's age. If both live for many years, there will come a day when the father's age will be only 1.5 times his son's age. This will happen in (A) 15 years. (B) 30 years. (C) 25 years. (D) 55 years. (E) 40 years. 🎥 FOLLOW ME ON SOCIAL MEDIA 📽 📲 YOUTUBE:    / mathematicallycomprofrobsonliers   📲 FACEBOOK:   / robsonliers.professor   📲 INSTAGRAM: (prof.robsonliers)   / prof.robsonliers   📲 SNAPCHAT: profrobsonliers 📲 EMAIL FOR PARTNERSHIPS: [email protected] ✅ CHANNEL PLAYLISTS: 🔴 HOW TO INTERPRET MATH PROBLEMS https://bit.ly/2RfMMPY 🔴 FRACTIONS AND PERCENTAGES https://bit.ly/2FazWO5 🔴 SIMPLE AND COMPOUND RULE OF THREE https://bit.ly/2KMOPK8 🔴 EXAM QUESTIONS https://bit.ly/2Rg0qmj 🔴 FIRST AND SECOND DEGREE EQUATIONS https://bit.ly/2IfmYk3 🔴 FIRST DEGREE EQUATION SYSTEM https://bit.ly/2MWP0oG 🔴 NOTABLE PRODUCTS https://bit.ly/2X8W45z 🔴 SIMPLE AND COMPOUND INTEREST https://bit.ly/2WAbxaE 🔴 GCD AND GCD https://bit.ly/2MM0dbO 🔴 MILITARY EXAMS (TESTS) https://bit.ly/2IewHXN 🔴 FEDERAL INSTITUTES (TESTS) https://bit.ly/2KNDtFD 🔴 PLANE GEOMETRY https://bit.ly/2RgzRxm 🔴 TRIGONOMETRY https://bit.ly/2XJoosl ⚠️ PROPOSED PROBLEM: 🔵NOW IT'S YOUR TURN! ✔ Sandro is now 5 times the age Carlos was 5 years ago.
