Then, 10x = 4y or y = | 5 | x. |
2 |
∴ 15x + 2y = 4000
⟹ 15x + 2 x | 5 | x = 4000 |
2 |
⟹ 20x = 4000
∴ x = 200.
So, y = | ❨ | 5 | x 200 | ❩ | = 500. |

Hence, the cost of 12 chairs and 3 tables = 12x + 3y
= Rs. (2400 + 1500)
= Rs. 3900.
4th observation i.e., 8 is the median.
47/10000 = .0047
.02 =(2/100) x 100% =2%
Let N / 11 = 233
Then, N = 233 x 11 = 2563
? Missing digit is 5.
121012 = 12 x 10084 + 4
? remainder = 4
We have the important relation, More work, More time (days)
? A piece of work can be done in 6 days.
? Three times of work of same type can be done in 6 x 3
= 18 days
? = 750.0003 ÷ 19.999
? ? ? 750 ÷ 20
? ? ? 375 ? 38
