Step-by-step solution for: 125 Simple Class 3 GK Questions, With Answers
You're absolutely right — the image you uploaded is an educational infographic titled “Brush Up Your Child’s General Knowledge” by *MomJunction*. It presents 6 general knowledge questions with their answers, designed to help children (and parents!) learn fun facts across science, history, geography, and human biology.
Let’s go through each question and answer with a clear explanation:
---
A: 150 million kilometers
🔹 Explanation:
This distance is known as 1 Astronomical Unit (AU). It’s the average distance from the center of the Earth to the center of the Sun. While the actual distance varies slightly due to Earth’s elliptical orbit (from about 147 million km at perihelion to 152 million km at aphelion), 150 million km is the standard rounded figure used for simplicity in education and general science.

A: Charles Babbage
🔹 Explanation:
Charles Babbage (1791–1871), an English mathematician and inventor, designed the first mechanical computers — the Difference Engine and the more advanced Analytical Engine. Though he never fully built them in his lifetime, his designs laid the conceptual groundwork for modern computing. That’s why he’s widely called the “father of the computer.”
> 📝 *Note:* Some may argue Alan Turing or others, but historically and in educational contexts, Babbage holds this title.
---
A: The Sahara Desert
🔹 Explanation:
The Sahara Desert, located in North Africa, covers about 9.2 million square kilometers — roughly the size of the United States. It’s not only the largest hot desert but also the third-largest desert overall (after Antarctica and the Arctic, which are cold deserts). Its extreme heat, vast sand dunes, and arid conditions make it iconic.
---
A: Archimedes
🔹 Explanation:
Archimedes of Syracuse (c. 287–212 BCE) was a Greek mathematician, physicist, engineer, and inventor. He made groundbreaking contributions to geometry, calculus (before its formal invention), buoyancy (“Eureka!”), and mechanics. His work on pi, levers, and pulleys earned him the title “Father of Mathematics” in many educational circles.
> ⚠️ *Some sources credit Pythagoras or Euclid*, but Archimedes is most commonly associated with this title due to the breadth and depth of his mathematical innovations.
---
A: April 22
🔹 Explanation:
Earth Day was first celebrated on April 22, 1970, founded by U.S. Senator Gaylord Nelson to raise awareness about environmental protection. Since then, it has become a global event, with over 1 billion people participating every year. It’s a day to promote sustainability, conservation, and climate action.
---
A: The femur bone
🔹 Explanation:
The femur (thigh bone) is the longest, strongest, and heaviest bone in the human body. In adults, it typically measures about 40–50 cm (16–20 inches) long and supports the body’s weight during walking, running, and jumping. It connects the hip to the knee and plays a crucial role in mobility.
