Question:
If 5 + 3 = 40, 6 + 4 = 60, then 3 + 2 = ?
यदि 5 + 3 = 40, 6 + 4 = 60, तो 3 + 2 = ?
Options:
- a) 25
- b) 20
- c) 16
- d) 15
- a) 25
- b) 20
- c) 16
- d) 15
correct answer : d)
Explanation:
The logic is: a + b = a * (a + b). So, 5*(5+3) = 40; 6*(6+4) = 60. Therefore, 3*(3+2) = 15.
तर्क है: a + b = a * (a + b)। अतः 5*(5+3) = 40; 6*(6+4) = 60। इसलिए, 3*(3+2) = 15।
