Researchers at the Indian Institute of Technology Guwahati (IIT Guwahati) recently developed an indigenous river model, BRAHMA-2D. BRAHMA-2D (Braided River Aid: Hydro-Morphological Analyzer) is a mathematical model to gauge the flow of large braided rivers like the Brahmaputra. It is a quasi-3D river flow model which helps to understand how fast the water moves at different depths inside a river and its circulation around a structure like a spur installed to prevent river bank erosion.
A and B together can complete a piece of work in 10 days. A alone can complete the work in 15 days. How many days will B take to complete the work alone?
A isfive times as efficient as B and can finish a piece of work in 36 days less than B. B can finish this work in how many days?
