Question 1 – If the cost of 7 m clothe is 294. Then find the cost of 5 m clothe?
Solution –
cost of 7 m clothe = 294 rupees
So the cost of 1 m clothe = 294÷ 7
= 42 rupees
Hence, cost of 5 m clothe = 42 * 5
= 210 rupees
Question 2 – Ekta earns 15000 in 10 days. How much will she earn in 50 days?
Solution –
Earning of 10 days = 15000 rupees
So, earning in 1 day = 15000÷ 10
= 1500
Hence, earning in 50 days = 1500* 50
= 75000 rupees.
Question 3 – if it has rained 276 mm in last 3 days. How many cm of rain will fall in one full week ( 7 days)? Assume that rain contiunes to fall at the same rate.
Solution-
Rain in 3 days = 276 mm
So, rain in 1 day = 276/3 = 92 mm
Hence, rain in 7 days = 92*7 = 644mm
So the rain in 7 days = 64.4 cm
Question 4 – cost of 5 kg of wheat is rupees 30.50.
(a) – what will be the cost of 8 kg of wheat?
(b) – what quantity of wheat can be purchased in rupees 61?
Solution –
Cost of 5 kg of wheat = 30.50
So, cost of 1 kg of wheat = 30.50/8 = 6.10 rupees
(a) Hence, cost of 8 kg wheat = 6.10*8
= 48.80 rupees
(b) quantity of wheat purchased from rupees 30.5 = 5kg
Quantity of wheat purchased from rupees 1 = 5/30.5
Quantity of wheat purachsed from rupees 61 = (5/30.5)*61
= 10 kg
