Answer 1

সঠিক উত্তর হচ্ছে: 240

ব্যাখ্যা: Suppose the daily wages of a man, a woman and a boy are 4k, 3k and 2k respectively. ∴ 15×4k+18×3k+12×2k=2070
⇒60k+54k+24k=2070⇒138k=2070⇒k=15 ∴ Daily wages of a man, a woman and a boy are Rs60,Rs45 and 30 Respectively,
∴ Daily wages of 1 man + 2 women + 3 boys =Rs 60+2×Rs 45+3×Rs 30=Rs 60+Rs 90+Rs 90=Rs 240
