A₹$1500$
B₹$1800$
C₹$2100$
D₹$2400$
Answer & Solution
Correct answer: B. ₹$1800$
**ପଦକ୍ଷେପ 1 — ଗୋଟିଏ ଭାଗର ମୂଲ୍ୟ।** ମୋଟ ଭାଗ $= 3 + 5 + 7 = 15$। ଗୋଟିଏ ଭାଗ $= \dfrac{5400}{15} = 360$। **ପଦକ୍ଷେପ 2 — B ଙ୍କ ଅଂଶ।** B ଙ୍କର $5$ ଭାଗ ରହିଛି $= 5 \times 360 = ₹1800$। **ଅନ୍ୟମାନଙ୍କ ଅଂଶ।** A ପାଆନ୍ତି $3 \times 360 = ₹1080$, ଏବଂ C ପାଆନ୍ତି $7 \times 360 = ₹2520$। ଏଗୁଡ଼ିକ B ଙ୍କ ଅଂଶ ନୁହେଁ।
