AI മാത്രം

BI ഉം II അല്ല

CII മാത്രം

DI ഉം II ഉം

Answer:

A. I മാത്രം

Read Explanation:

ചോദ്യപ്രകാരം X ↔ - എന്നും 2 ↔ 5 എന്നും മാറ്റണം.


I.

10 ÷ 2 X 3 + 5 - 6 = 11

മാറ്റിയാൽ:
10 ÷ 5 - 3 + 2 X 6

ഇപ്പോൾ കണക്കാക്കാം:
10 ÷ 5 = 2
⇒ 2 - 3 + 2 × 6
⇒ 2 - 3 + 12
⇒ -1 + 12 = 11


II.

5 X 4 + 2 - 6 ÷ 3 = 11

മാറ്റിയാൽ:
2 - 4 + 5 X 6 ÷ 3

കണക്കാക്കാം:
5 × 6 = 30
30 ÷ 3 = 10
⇒ 2 - 4 + 10
⇒ -2 + 10 = 8 ≠ 11


ശരിയായത്: I മാത്രം
