Question

-3 upon 8 multiple 28 upon 25 subtract -3 upon 8 multiple 3 upon 25​

Answer 1

Answer:

Step-by-step explanation:

According to the question,

⇒ Total temperature of first four days

Mon + Tue + Wed + Thu

= 25 × 4 = 100°C.....(i)

⇒ Total temperature of last four days

Thu + Fri + Sat + Sun

= 25.5 × 4 = 102°C .....(ii)

⇒ Total temperature of week

= 25.2 × 7 = 176.4°C .....(iii)

After adding equation (i) + (ii)

Mon + Tue + Wed + 2 × Thu + Fri + Sat + Sun

= 100° + 102° = 202°C.....(iv)

After subtracting equation (iv) - (iii)

= 202° - 176.4° = 25.6° C

⇒ Temperature of 4th day = 25.6° C

Answer 2

$(\frac{ - 3}{8} \times \frac{28}{25}) - (\frac{ - 3}{8} \times \frac{3}{25}) \\ \frac{ - 21}{50} - \frac{ - 9}{200} \\ \frac{ - 2100 - ( - 9)}{200} \\ \frac{ - 2091}{200} \\ 10 \frac{91}{200}$
