At 'Gati' Center, the standards for a handset are: 2 OLED screens at 4,000 each; 3 labor hours at 600 per hour. Variable overhead is 300 per labor hour. August output was 9,500 handsets. Purchased: 20,000 screens for 78,000,000. Used: 19,200 screens. Labor paid: 29,000 hours (includes 500 hours idle time) for 17,980,000. Based on this, calculate the Material Price Variance (on purchase), Material Usage Variance, and Labor Efficiency Variance.

A manufacturing company has established standard costs for one of its products. The standard quantity of material required per unit is 5 kg at a standard price of ₹4 per kg. During a particular month, the company produced 1,000 units and used 5,500 kg of material at an actual price of ₹5 per kg. In addition, the standard labor time per unit is 2 hours at ₹10 per hour, but actual labor hours worked were 2,200 hours at ₹12 per hour. Which of the following statements are correct regarding variances? 1. Material Price Variance is adverse. 2. Material Usage Variance is adverse. 3. Labour Rate Variance is favourable. 4. Labour Efficiency Variance is adverse. Select the correct answer using the code below:

A company requires 5 kg of raw material for 1 unit of finished product, at a standard price of 400 per kg. It produced 2,000 units and consumed 10,500 kg of raw material, costing 4,095,000. Calculate the Material Usage Variance using the standard mathematical sign convention.
