നൽകിയിരിക്കുന്നത്:

ചെറിയ സംഖ്യ = 24 

കണക്കുകൂട്ടൽ:

വലിയ സംഖ്യ = a ആകട്ടെ

സംഖ്യകളുടെ വ്യത്യാസം = a - 24

ചോദ്യം അനുസരിച്ച്;

(a + 24) = 5(a - 24)

⇒ a + 24 = 5a - 120

⇒ 144 = 4a 

⇒ a = 36

∴ വലിയ സംഖ്യ 36 ആണ്.

Alternate Methodഹിറ്റ് ആൻഡ് ട്രെയിൽ രീതി പ്രകാരം

ഓപ്ഷൻ 1: (24 + 30) ≠ 5(30 - 24)

ഓപ്ഷൻ 2: (24 + 32) ≠ 5(32 - 24)

ഓപ്ഷൻ  3: (24 + 36) = 5(36 - 24) = 60 

ഓപ്ഷൻ 4: (24 + 48) ≠ 5(48 - 24)
