The Correct Option is D
Solution and Explanation
Step 1: Understanding the Concept:
અંકગણિતીય વૃદ્ધિ (Arithmetic Growth) નું સૂત્ર: $L_t = L_0 + rt$, જ્યાં $L_t$ = અંતિમ લંબાઈ, $L_0$ = પ્રારંભિક લંબાઈ, $r$ = વૃદ્ધિ દર અને $t$ = સમય.
Step 2: Calculation Steps:
$L_0 = 20$ સેમી
$r = 30$ સેમી/દિવસ
$t = 7$ દિવસ
$L_7 = 20 + (30 \times 7)$
$L_7 = 20 + 210 = 230$ સેમી.
Step 3: Final Answer:
7મા દિવસના અંતે તણાની લંબાઈ 230 સેમી હશે.
