The given bar graph shows the sales of cars from six branches of a dealer B1, B2, B3, B4, B5, B6, during two consecutive years 2018 and 2019. The 1st bar corresponds to the year 2018 and the 2nd bar corresponds to the year 2019. In the bar graph, the ratio of the total sales from branches B1, B2 and B3 taken together for the year 2018 to the sales from the branches B6, B4 and B5 for the year 2019, is:
In a survey conducted in a city, it was found that 25% of the people going to a bar on Saturday were females. But, the number of females going to the bar on Sunday is 80% less than that on Saturday. If the total number of people going to the bar on Sunday decreased by 50% as compared to that on Saturday, what is the percentage decrease in the number of males going to the bar on Sunday as compared to Saturday?
An aluminium bar of 8 m length and a steel bar of 5 mm longer in length are kept at 30°C. If the ambient temperature is raised gradually, at what temperature the aluminium bar will elongate 5 mm longer than the steel bar (the linear expansion coefficients for steel and aluminium are 12 × 10-6/°C and 23 × 10-6/°C respectively)?

A steel and a copper bar are joined end to end. The area of the steel bar is half the area of the copper bar. Their lengths are equal to 10cm each. Temperature of free ends of steel & copper rod are 0°C & 100°C respectively. KS = 50 J/smK & KC =384 J/smK. Calculate equivalent thermal conductivity of the combined bar.
The length, Young’s modulus and coefficient of thermal expansion of bar P are twice that of bar Q. what will be the ration of stress developed in bar P to that in bar Q if the temperature of both bars is increased by the same amount?
