Solve these word problems: 1. Shantanu's friend bought a shirt for 1962 rupees. If he had 2319 rupees, how much is left? 2. A school has 5324 students. If there are 1973 boys, how many girls are there

Initial amount: 2319 rupees
Cost of shirt: 1962 rupees
Amount left = Initial amount - Cost of shirt

$$2319 - 1962 = 357$$

Shantanu's friend has 357 rupees left.

Total students: 5324
Number of boys: 1973
Number of girls = Total students - Number of boys

$$5324 - 1973 = 3351$$

There are 3351 girls in the school.

Initial number of jeans: 7923
Number of jeans sold: 5986
Number of jeans left = Initial number of jeans - Number of jeans sold

$$7923 - 5986 = 1937$$

The shopkeeper has 1937 jeans left.
