Find the product: (30 gallons 3 quarts 1 pint) × 5

SpyIntel [72]

30 gallons * 5 = 150 gallons

3 quarts * 5 = 15 quarts

1 pint * 5 = 5 pints

Four quarts in a gallon: 15/4 = 3 gallons, 2 quarts

2 pints in a quart: 5/2 = 2 quarts, 1 pint

2 quarts + 2 quarts = 1 gallon

150 + 3 + 1 gallons + 1 pint = 153 gallons, 1 pint.

1) The cost of constructing a path 5 m broad inside the boundary of a square lawn at Rs 36.25 per sq. metre is Rs 90625. What is

Svetach [21]

Let , side lawn is a.

Area of boundary is :

$A=4\times5\times a\\\\A=20a\ m^2$

Now, total cost is given by :

$T=20a\times 36.25\\\\90625=725a\\\\a=125\ m$

Area left is :

$A'=a^2-20a\\\\A'=125^2-20\times 125\ m^2\\\\A'=13125\ m^2$

Price to empty space with turfs is :

$P=A'\times 20\\\\P=13125\times 20\\\\P=262500$

Therefore, the cost of covering the empty space with turfs at the rate of Rs 20 per sq. metre is Rs 262500.

Hence, this is the required solution.
