Q1. Shreya went to a fair in her village. She wanted to enjoy rides on the giant wheel and play hoopla. If each ride costs Rs 3 and a game of hoopla costs Rs 4 then she spent Rs 20. Find the linear equation to represent this condition. Q2. The cost of fencing a circular field at the rate of Rs. 36 per m is Rs. 11880. The field is to be ploughed at the rate of Rs. 0.60 per Meter square. Then, find the cost of ploughing the field. Q3. There are 1000 sealed envelopes in a box, 10 of them contain a cash prize of Rs 100 each, 100 of them contain a cash prize of Rs 50 each and 200 of them contain a cash prize of Rs 10 each and rest do not contain any cash prize. If they are well- shuffled and an envelope is picked up out, then find the probability that is contains no cash prize.
