个体户王小二承接了建筑公司一项运输1200块玻璃的业务，并签了合同。合同上规定：每块玻璃运费2元；如果运输过程中有损坏，每损坏一块，除了要扣除一块玻璃的运费外，还要赔25元。王小二把1200块玻璃运送到指定地点后，建筑公司按合同付给他2076元。问：运输过程中损坏了多少块玻璃( )
A．10
B．12
C．14
D．24
参考答案：B
解析： 如果一块玻璃也不损坏，那么，王小二可得运费2×1200=2400(元)。而王小二实际得运费2076元，两者相差2400-2076＝324(元)。 由于在运输过程中每损坏一块玻璃，不仅得不到2元的运费，还要赔偿25元。因此，每损坏一块玻璃就要少收入2+25＝27(元)。所以，求王小二损坏了几块玻璃，就是求他一共少收入的324元中有几个27元。 324÷27＝12(块)，所以，在运输过程中共损坏了12块玻璃。
