Simple Interest Test (with Figures)
सरळव्याज टेस्ट (आकृतीसह)
20 Questions / २० प्रश्न • 1 mark each / प्रत्येकी १ गुण
Useful formulas / उपयुक्त सूत्रे:
• P = Principal (मुद्दल), R = Rate % per year (द.सा.द.शे. = दर साल दर शेकडा), T = Time in years (मुदत), SI = Simple Interest (सरळव्याज), A = Amount (रास).
• SI = P × R × T ÷ 100 • A = P + SI (रास = मुद्दल + व्याज).
• P = SI × 100 ÷ (R × T) • R = SI × 100 ÷ (P × T) • T = SI × 100 ÷ (P × R).
• Change months into years before using the formula: 6 months = ½ year, 3 months = ¼ year. / महिन्यांचे वर्षात रूपांतर करा: ६ महिने = ½ वर्ष.
• "द.सा.द.शे. 5" means ₹100 earns ₹5 interest in 1 year. / द.सा.द.शे. ५ म्हणजे ₹१०० वर १ वर्षाला ₹५ व्याज.
• Simple interest is the same every year, because it is always calculated on the original principal. / सरळव्याज दरवर्षी सारखेच असते.
• In the figures: the three boxes show P, R, T; the arrow leads to the answer; a red ? is the unknown; in bar figures the red bracket is the whole. / आकृतीत लाल ? अज्ञात आहे.
