Explanation

Total weight of (36 + 44) Students,

= (36 × 40 + 44 × 35) kg

= 2980 kg

Therefore average weight of the whole class,

= 298080 kg.

Therefore average weight = 37.25 kg.

Explanation

Total cartons = 5 + 8 = 13

Total cost = 105 + 155 = 260

Total items = 13 x 5 = 65

Average price per item = Total cost / Total items = 260 / 65 = 4

Explanation

Let number of boys are x and then number of girls
= (100 - x)
Thus,
50x + (100 - x) × 40 = 46 × 100
→ x = 60
Number of boys = 60

Explanation

Full tank capacity = Distance ÷ Miles per gallon

= 250 miles ÷ 15 miles/gallon

= 16.67 gallons (approximately)

Now, if the car gets 20 miles per gallon, we can calculate the distance it can travel on a full tank:

Distance = Full tank capacity × Miles per gallon

= 16.67 gallons × 20 miles/gallon

= 333.4 miles

Explanation

To calculate the compound interest, we need to calculate the interest for each year and add it to the principal.

Year 1:

Principal = Rs. 1875

Rate = 4%

Interest = (1875 x 4)/100 = Rs. 75

Amount = Principal + Interest = 1875 + 75 = Rs. 1950

Year 2:

Principal = Rs. 1950 (amount after 1st year)

Rate = 8%

Interest = (1950 x 8)/100 = Rs. 156

Amount = Principal + Interest = 1950 + 156 = Rs. 2106

Now, let's calculate the compound interest:

Compound Interest = Amount - Principal = 2106 - 1875 = Rs. 231
