6The cost price of 30 articles is equal to theselling price of 25 articles. Find the loss orgain percent. |
Answer» Answer:
Step-by-step EXPLANATION:Given:
To Find:
Let each articles price is Rs. 1. So, => CP of 30 articles = Rs. 30 = SP => SP of 25 articles = Rs. 25 = CP So, Gain = SP - CP => Gain = 30 - 25 => Gain = Rs. 5 Now, we will find Gain Percentage, => Gain % = Gain/SP × 100 => Gain % = 5/25 × 100 => Gain % = 0.2 × 100 => Gain % = 20% Hence, Gain % = 20%. |

How many tiles measuring 20cm.20cm each will be required to pave a 1.5m wide footpath around a grassy plot of 25m.16m? |
|
Answer» Answer: 3300 tiles Step-by-step explanation: first find the area of the footpath it will be theatres of grassy plot SUBTRACTED from the total area(plot and FOOT path) area of plot is 25×16 which is 400m square total area is 28×19 (25+3 is the length with the footpath and 16+3 is the breath with footpath) which is 532m square area of foot path is 532-400=132m square now to convert it into cm square we multiply the area with10000 so the area in cm square is 1320000 cm square now LET us find the area of the tiles area of tiles is 20×20=400cm square to find the NUMBER of tiles required we should divide the area of footpath by the area of tiles 1320000cm square ÷ 400cm square so the number of tiles required is 3300 |
