13 - [10 - {16 + 8 ÷ (k - 2)} + 2] = 20
ఉపయోగించిన భావన:
సాధన:
13 - [10 - {16 + 8 ÷ (k - 2)} + 2] = 20
⇒ - [10 - {16 + 8 ÷ (k - 2)} + 2] = 20 - 13
⇒ - [10 - {16 + 8 x 1/(k - 2)} + 2] = 7
⇒ - [10 - {16(k - 2) + 8}/(k - 2) + 2] = 7
⇒ - [{10(k - 2)} - {16 (k - 2) + 8} + {2(k - 2)}] = 7(k - 2)
⇒ - [10k - 20 -16 k + 32 - 8 + 2k - 4] = 7k - 14
⇒ 4k = 7k - 14
⇒ 3k = 14
⇒ k = 14/3
∴ సరైన సమాధానం 14/3.
